                               NATURE OF AGREEMENT

                  1A.1 PURPOSE AND SCOPE OF THIS AGREEMENT.  The purpose of this
Agreement  is to permit  Supplier  to provide  and  Ordering  Company to receive
Supplier's  Products,  Licensed  Materials,  and Services.  This Agreement shall
govern all transactions  pursuant to which Supplier provides Products,  Licensed
Materials  and Services to AT&T and Ordering  Companies.  AT&T and Supplier will
develop a  template  no later than June 30,  1996 for use when AT&T or  Ordering
Company is ordering  Products,  Licensed  Materials  and Services  from Supplier
pursuant to this Agreement for use outside the United States. This template will
be used as the  starting  point for  Supplemental  Agreements  to  address  such
purchases and will address the additional  country and  customer-specific  terms
and requirements  with the particular  transaction.  This Agreement shall govern
Supplier's  sale and  licensing to Ordering  Companies of  Supplier's  Products,
Licensed Materials and Services for Ordering  Companies'  internal business uses
only,  and does not permit AT&T to resell or sublicense  any Products,  Licensed
Materials or Services provided hereunder as a distributor of same. However, this
Agreement,  including  any  restrictions  on use,  resale  and  transfer  is not
intended to prohibit  Ordering  Company from reselling or transferring  Products
and Licensed  Materials  no longer  needed for the  operation  of its  business,
provided,  that, in the case of Software,  such transfers are made in accordance
with the provisions of Article 9. All terms and conditions  governing  resale or
sublicensing  of  Supplier's  Products,  Licensed  Materials  and  Services as a
distributor shall be addressed in a separate agreement.







This  Agreement  is  organized in the  following  manner:  Part 1 sets forth the
common  terms and  conditions  that  apply to all sales  and  licenses  executed
pursuant to this Agreement, unless otherwise stated in Part 2. Part 2 sets forth
the additional terms and conditions which govern Supplier's provision of network
infrastructure Products,  Licensed Materials and Services, other than such items
currently provided by Supplier's Business  Communications Systems business unit,
previously known as "GBCS," ("BCS").  Part 3 sets forth the additional terms and
conditions which govern Supplier's provision of Products, Licensed Materials and
Services provided by BCS.

                  1A.2 STATEMENT OF ASPIRATIONS. In an effort to ensure that the
parties remain fully focused upon their shared  objectives and aspirations,  the
parties  agree that the  following  principles  shall govern their work together
during the term of this Agreement:


                (a) Both parties want Lucent  Technologies  Inc.
to provide AT&T
with Products,  Licensed  Materials and Services that confer
significant  offer
differentiation,  premium value and operating  cost  reduction
consistent  with
AT&T's brand equity, and shall work together so that Lucent
Technologies Inc.
may assist AT&T in this manner;



                  (b) The parties recognize that Supplier's pricing of Products,
Licensed  Materials  and  Services  must balance two  fundamental  requirements:
AT&T's  requirement  for the  lowest  possible  operating  costs and  Supplier's
requirement for adequate return on and recovery of investment;

                  (c) The  parties  shall  at all  times  take  care to  conduct
themselves with the highest integrity, to respect all individuals, and to obtain
the maximum benefits of a shared end user customer focus, effective teamwork and
the parties' innovativeness; and

                  (d) The  parties  desire to  maintain a
relationship  that is
warm, open and mutually profitable.

                  1A.3 VOLUME  COMMITMENT.  (a) AT&T commits that the  aggregate
amount paid by Ordering  Companies  (including  AT&T Wireless  Services Inc.) to
Supplier during the calendar years 1996,  1997, and 1998 for Products,  Licensed
Materials, and Services, pursuant to this Agreement, any Supplemental Agreement,
any other agreement or otherwise,  between an Ordering  Company and Supplier for
Supplier's provision of Products,  Licensed Materials or Services to an Ordering
Company,  will total at least three billion  dollars  ($3,000,000,000).  If that
commitment is not  fulfilled by December 31, 1998,  Supplier  shall,  in January
1999,  bill AT&T a carrying  charge equal to the shortfall at December 31, 1998,
multiplied  by the Prime Rate (as  defined in the  Separation  and  Distribution
Agreement) plus two percent (2%).  Thereafter,  Supplier shall, each month, bill
AT&T a  carrying  charge  equal  to the  shortfall,  if  any,  at the end of the
preceding  month,  multiplied  by 1/12  multiplied  by the  Prime  Rate plus two
percent  (2%).  Such  billing  shall  continue  until the three  billion  dollar
($3,000,000,000) commitment is fulfilled. AT&T will pay these bills as set forth
in Section 3.2, INVOICES AND TERMS OF PAYMENT.  The remedy in this Section 1A.3,
VOLUME COMMITMENT, is






Supplier's  exclusive  remedy for AT&T's  failure to fulfill  the three  billion
dollar ($3,000,000,000) volume commitment.

                  (b) AT&T expects, but does not commit, that Products, Licensed
Materials  and  Services  in the amount of one  billion  three  hundred  million
dollars  ($1,300,000,000),  out of the three  billion  dollar($3,000,000)  total
volume commitment, will be ordered in 1996. Therefore, the shortfall billing and
payment  arrangement  set  forth in  subparagraph  (a)  above  does not apply to
failure to meet this expectation by the end of 1996.

                  (c) Prior to the Closing  Date (as  defined in the  Separation
and Distribution  Agreement),  AT&T shall deliver to Supplier as advance payment
for purchases of Products,  Services,  Software, or Licensed Materials an amount
equal to five hundred million dollars  ($500,000,000).  Commencing on January 1,
1997,  Supplier  shall  apply a portion of such  amount as a credit  against any
undisputed  invoiced  amounts due and payable to Supplier  from AT&T or, if AT&T
shall so  specify  at any time,  from any other  Ordering  Company,  on or after
January 1, 1997, in full  satisfaction  of all  obligations  of AT&T or any such
Ordering Company then due in connection therewith. Supplier shall continue to so
apply such advance  payment as a credit against such  undisputed  invoices until
fully applied.

                 1A.4 GOVERNING  TERMS.  (a) Current Order  Performance:  On the
Effective Date of this Agreement, Supplier shall be in the process of performing
several  Ordering  Company  orders,  some of which have not been the  subject of
written Orders and purchase agreements. In addition, Supplier shall be following
many existing engineering, installation and maintenance practices and procedures
that have been developed  mutually by Supplier and Ordering Company but have not
been completely  documented.  The parties intend that Supplier shall continue to
provide the same  Products,  Services and Licensed  Materials  which Supplier is
providing or has agreed to provide each Ordering Company  (hereinafter  "Pending
Orders") subject to the availability of third party components and provided that
Ordering  Company  shall  retroactively  compensate  Supplier for any  Products,
Licensed Materials and Services provided by Supplier without compensation at the
prices  and  rates  set  forth  in any  mutual  agreements  entered  into.  Such
retroactive  compensation  shall begin no earlier  than the  Effective  Date and
shall be capped at twenty  million  dollars  ($20,000,000)  per month.  Supplier
shall not be liable  for any  injury  to  Ordering  Company  that  results  from
Supplier's  employees  and/or  contractors  failure to be aware of practices and
procedures  that had not, at the time of  Supplier's  actions,  been  reduced to
writing. Supplier and Ordering Company recognize that the existing practices and
procedures  will need to be reevaluated in light of the  restructure of AT&T. As
part of this reevaluation,









Supplier  and Ordering  Company may decide to continue  existing  practices  and
procedures  or one  party  may  notify  the  other  that it  wishes to change or
eliminate certain practices or procedures.


The  parties  agree to use their best  efforts to identify  any other  Products,
Licensed  Materials and Services  provided by Supplier to Ordering  Company that
require  commercialization and to formalize such undocumented  arrangements in a
commercially  reasonable manner that is consistent with the terms and conditions
contained herein no later than March 31, 1996. The parties acknowledge that such
formalization  and  modification of those  arrangements may result in changes in
the terms  and  conditions  pursuant  to which  such  items  are  provided.  All
agreements  will be reduced to writing  which will govern  transactions  between
Supplier and all Ordering Companies,  unless otherwise agreed to. If the parties
are unable to  negotiate  a  satisfactory  resolution,  the  dispute  resolution
provisions of Article 5A herein shall apply. Services not currently performed by
Supplier are not covered under this Section 1A.4,  GOVERNING  TERMS, and will be
covered under separate Supplemental Agreements.

With respect to Pending  Orders,  this Agreement is  incorporated  by reference,
however,  in the event of  conflict  between  the terms and  conditions  of this
Agreement  and the  terms  and  conditions  of  Pending  Orders,  the  terms and
conditions of Pending Orders shall prevail over the terms and conditions of this
Agreement until such time that the Pending Orders are formalized,  terminated or
expired.

                  (b) Future  Procurements:  All future Orders and  Supplemental
Agreements pursuant to which Supplier provides Products,  Licensed Materials and
Services to AT&T Company  shall be deemed to  incorporate  and be subject to the
terms and conditions of this Agreement,  regardless of whether any such Order or
Supplemental  Agreement  expressly  incorporates  this  Agreement by  reference,
unless such Order or Supplemental  Agreement  expressly  provides that it is not
subject to this  Agreement.  To the extent that any exhibit to this Agreement or
any document other than a Supplemental Agreement conflicts with the body of this
Agreement,  the body of this Agreement  shall prevail over such exhibit or other
document.  To the  extent  that a  Supplemental  Agreement  conflicts  with this
General Purchase  Agreement,  the Supplemental  Agreement shall prevail over the
body of this Agreement.  To the extent that the  Supplemental  General  Purchase
Agreement,  No.  LC3757D,  conflicts with either or both of this Agreement and a
Supplemental  Agreement,  the  Supplemental  General  Purchase  Agreement  shall
prevail over those other agreements.

                 1A.5 TERM OF AGREEMENT.  This Agreement shall become  effective
on the  Effective  Date and shall  continue  in effect  for a period of five (5)
years. The term of this Agreement shall thereafter be automatically extended for
additional one (1) year periods unless either party provides the other party one
(1) year's prior written notice of its desire to permit this Agreement to expire
without  further  extension  of its term,  in which event this  Agreement  shall
expire  on the day  before  this  Agreement  would  otherwise  be  automatically
extended.  The amendment or termination  of this Agreement  shall not affect the
obligations of an Ordering  Company or Supplier under any then existing Order or
Supplemental Agreement issued under this Agreement.







                  1A.6 TRANSITION  PERIOD.  Although all terms of this Agreement
are  effective  on the  Effective  Date,  the parties  recognize  that  complete
implementation  of certain terms depends upon the  development and deployment of
necessary practices and systems. Those terms include, but are not limited to:

                  -  Section  2.1 -  Orders  -  Section  2.2 -
Order  Acceptance
                  Section  2.6 - Order  Cancellation  and  Holds
- -  Section  3.1
                  Pricing - Section 3.2 - Invoices and Terms of
Payment  Section
                  5.1 -  Ordering  Companies  Remedies  - Section
5.2  Supplier
                  Performance  - Section 6.21 - Record  Retention
- - Section 8.16
                  Planning Information for Orders for
                         Commercially Available Products

Both parties  agree to use their  reasonable  best efforts to develop and deploy
those  practices  and  systems  underlying  these and other terms as promptly as
possible,  but not later than March 29, 1997.  The  inability of either party to
comply with any of these terms as a result of not having  developed and deployed
such  practices  and systems  prior to March 29,  1997,  will not be construed a
breach  of  contract,  provided,  however,  that if  such  Supplier's  delay  in
developing  and  deploying  necessary  practices  and systems  delays  affording
Ordering  Company the benefits of the Pricing  Agreement,  Supplier shall afford
those benefits to Ordering Company, as promptly as possible,  retroactive to the
Effective Date.

                  1A.7 PURCHASES BY AT&T'S AFFILIATES. This
Agreement shall
govern purchases from Supplier by AT&T, its Affiliates and
Ordering Companies,
but shall not govern purchases by other entities.

                  1A.8 ADDITIONAL TECHNOLOGY RIGHTS. Supplemental Agreements may
provide,  on a case-by-case  basis, for Ordering Company's  ownership (up to and
including  100%  ownership)  of  specified   intellectual   property  rights  in
technology newly developed by Supplier solely on behalf of Ordering Company.  In
the event technology is licensed by Supplier to Ordering  Company,  Supplier may
agree to grant  Ordering  Company (a) the right to make,  have made,  use, sell,
modify,  offer for sale or  import  specified  Products  and  provide  specified
Services  and  (b)  the  title  and  intellectual  property  rights  to  certain
modifications and resulting derivative works made by Ordering Company.

Agreement,  or any other subordinate document (such as a shipping release) shall
be binding,  except data  necessary  for Supplier to fill the Order.  Electronic
Orders  shall be binding on Ordering  Company  notwithstanding  the absence of a
signature.   All  schedules  and  requested  dates  are  subject  to  Supplier's
concurrence.

                  (c) For  construction  Services,  Ordering Company shall place
Orders at an agreed upon time period prior to the applicable  construction start
date. In the event that Ordering Company is not ready to receive shipment on the
scheduled  delivery  date,  Ordering  Company shall  reimburse  Supplier for any
reasonable warehousing,  handling, hoisting and idle time costs sustained during
the delay period.

                  2.2 ORDER ACCEPTANCE.  All Orders are subject to acceptance by
Supplier.  Supplier  shall  have  twenty-one  (21)  business  days in  1996  and
thereafter  ten (10)  business  days after the  receipt of the Order in which to
notify  Ordering  Company of those  aspects of  Ordering  Company's  Order which
Supplier is unable to accept and to provide  Ordering  Company  Supplier's  firm
schedule  Completion  Date for the Order.  Failure to provide such notice within
that period shall be deemed  acceptance of Order.  Ordering  Company or Supplier
may modify the terms or content of any Order if such changes are mutually agreed
to and documented in writing.

                  2.3  CHANGES IN ORDERING  COMPANY'S  ORDERS.  Should  Ordering
Company wish to obtain information  sufficient to permit it to assess whether to
submit an Order adding, deducting or deviating from a prior Order (hereinafter a
"Change Information  Request"),  it shall request such information from Supplier
in writing.  As promptly as  reasonably  possible  after its receipt of a Change
Information Request,  Supplier shall submit a proposal to Ordering Company which
includes  any  increases  or  decreases  in  Supplier's  Price or changes in the
delivery or work  schedule for the existing and new Orders  necessitated  by the
change. Unless Supplier receives an Order to implement such change from Ordering
Company within  twenty-one (21) calendar days of Ordering  Company's  receipt of
Supplier's proposal, Ordering Company shall be deemed not to have authorized the
change and Supplier  shall remain  obligated to perform all  previously  ordered
work in  accordance  with (a) the  governing  Order  (for  Products)  or (b) for
Licensed Material,  the governing Order or appropriate  Supplemental  Agreement.
Changes by Ordering  Company to an accepted Order shall be treated as a separate
Order only if such  change  materially  affects  Supplier's  ability to meet its
obligations  under the original Order, in which case any Price (or discount,  if
applicable), shipment date or Services Completion Date provided by Supplier with
respect to such original Order shall be subject to change.

                  2.4 CHANGES IN PRODUCTS BY SUPPLIER.  Any change that Supplier
proposes  to the  Product  furnished  hereunder  and the  documentation  related
thereto would be subject to the Change Notice Process attached hereto as Exhibit
2-2.






                  2.5 ORDER CANCELLATION AND HOLDS.

                  (a) CANCELLATION FOR CONVENIENCE.

                           (i)  Ordering  Company may,  upon
written  notice to
         Supplier, cancel an Order, provided that Ordering Company
shall pay the
         applicable  fees, if any, set forth in Paragraphs  (ii),
(iii) and (iv)
         below.

                           (ii)  For  those  Products  and
Licensed   Materials
         canceled  prior to shipment that are considered  stock
items,  Ordering
         Company  agrees that it shall pay  Supplier an Order
cancellation  fee
         equal to fifteen  percent  (15%) of the Price or
license  fee for such
         items.

                           (iii)  For  those  Products  and
Licensed  Materials
         considered to be customized or non-stock items (1) not
manufactured or
         (2) manufactured but not yet accepted, Ordering Company
shall pay a fee
         based  upon  Supplier's   incurred   expenses  (after
adjustment  for
         recoveries and/or salvage value, if any), including, but
not limited to
         de-installation,    transportation    and   associated
general   and
         administrative expenses, plus a reasonable profit in the
event that the
         customized or non-stock  items are not  ultimately  sold
or licensed to
         another  party within ninety (90) days of  cancellation,
provided that
         Supplier has made a reasonable attempt to sell or license such items.

                           (iv) If an Order for Services is
canceled in whole or
         in part  after  execution  of such  Order  and  prior to
the  scheduled
         completion of such  Services,  Ordering  Company agrees
to pay Supplier
         the fees due for  Services  provided  (which fees,
depending  upon the
         specific  terms  of the  agreement,  may  be  based  on
the  applicable
         periodic rates or equal to the percentage of the
contracted  project or
         period  that  Supplier  has  completed  multiplied  by
the  total  fee,
         excluding expenses, for such project or period) and all
expenses of any
         type  incurred  for  performing  the  Services  prior  to
the  date  of
         cancellation  and any expenses  Supplier may incur for
terminating the
         Services, including but not limited to:

                                    (A) the cost of materials
(less salvage
         value,  if any) which have been delivered to the work
site prior to the
         date of termination  but which have not yet been
incorporated  into or
         been consumed in performing the Services; plus

                                    (B) the cost of undelivered
materials (less
         salvage value, if any) planned for use in performance of
this Agreement
         for which irrevocable Work Orders have been placed by
Supplier prior to
         the effective date of cancellation; plus

                                    (C) the cost of any other
capital
         expenditure  that has been incurred in order to perform
the  terminated
         project and that  cannot be  re-applied  by  Supplier to
provide  other
         Services; plus






                                    (D) the cost to Supplier of
terminating and
         settling any subcontracts.

                           (v) For purposes of this  subparagraph
(a), "salvage
         value"  shall  include  the  proceeds  of the sale of
the  material  to
         another  Ordering  Company and the costs Supplier avoids
as a result of
         its reapplying  materials to meet other needs of Ordering
Company,  the
         needs of other  customers or its own internal  needs
within ninety (90)
         days of Order  cancellation.  Supplier shall make
reasonable efforts to
         maximize   salvage   value.   Upon  written   request,
Supplier  will
         substantiate such avoided costs.

                  (b) HOLDS.  Ordering  Company  may issue  "holds" on Orders or
suspend  performance  under this  Agreement,  in whole or in part,  upon written
notice to Supplier and shall  compensate  Supplier for any  incremental  expense
(including, but not limited to, warehousing, loss, damage and inventory carrying
costs) incurred.  A hold  automatically  converts to an Order cancellation after
thirty (30) days.

                  (c)  CANCELLATION FOR CAUSE. In the event Supplier shall be in
material breach or default of any of the terms, conditions,  or covenants of any
Order or Supplemental Agreement and if such breach or default shall continue for
a period of forty-five  (45) days in 1996 and thereafter  thirty (30) days after
Supplier's  receipt of notice thereof by Ordering Company,  then, in addition to
the remedies specified in Section 5.1, ORDERING  COMPANIES'  REMEDIES,  Ordering
Company  shall have the right to cancel  such Order or  Supplemental  Agreement,
except  to the  extent  that  Products,  Licensed  Materials  or  Services  have
previously been provided pursuant to such Order or Supplemental Agreement.

                  (d) SURVIVAL. The obligations of this Section
2.5 shall
survive termination of this Agreement.

                  2.6 SHIPPING,  PACKING AND DELIVERY. (a) Supplier shall, at no
additional  charge,  pack Products in accordance with its standard practices for
shipments  to Ordering  Company's  locations.  Unless  instructed  otherwise  by
Ordering  Company,  Supplier shall (i) ship Orders as available,  but not before
the customer requested ship date, (ii) ship to the destination designated in the
Order, (iii) mark all subordinate  documents with the Order number, (iv) enclose
a packing  memorandum  with each  shipment,  and when more than one  package  is
shipped,  identify the package containing the memorandum,  and (v) mark Ordering
Company's Order number on all packages and shipping papers.

                  (b)  Where,  in order  to meet  Ordering  Company's  requests,
Supplier packs Products in other than its normal manner,  Ordering Company shall
pay Supplier's  additional  charges for such packing.  Absent written  agreement
otherwise,  Supplier  will deliver  Products and Licensed  Materials to Ordering
Company  FOB  (free  on  board)  the   manufacturing,   warehouse   or  Software
distribution facility of Supplier or its vendor.






                  (c) Unless otherwise  directed by Ordering  Company,  Supplier
shall (i) ship equipment from its nearest facility or that of its vendor capable
of filling the Order, (ii) use the lowest available rate from Ordering Company's
pre-selected  designated carrier (rail, truck or freight  forwarder),  and (iii)
prepay  transportation  charges at cost as a separate item on Ordering Company's
invoice  when the cost of  transportation  is to be borne by  Ordering  Company.
Ordering  Company  shall  promptly  pay to Supplier  any prepaid  transportation
charges.  Supplier will provide to Ordering Company a transportation factor card
to  be  used  for  estimating   transportation   rates.   Shipping  and  routing
instructions may be furnished or altered by Ordering Company in writing, subject
to additional charges, if applicable.

                  (d) Supplier agrees not to deliver  Products prior to five (5)
business days before the agreed upon delivery date without Ordering Company's
prior written authorization.

                  2.7  TITLE  AND  RISK OF  LOSS.  Title  to and risk of loss to
Products and risk of loss of Licensed  Materials shall pass to Ordering  Company
upon delivery to Ordering Company. For purposes of this clause, "delivery" shall
mean the point at which  Supplier  or  Supplier's  supplier  or agent turns over
possession of the Product or Licensed  Materials to Ordering  Company,  Ordering
Company's employee, Ordering Company's pre-selected designated carrier, Ordering
Company's  warehouse,  or other Ordering Company's agent and not necessarily the
final  destination  shown on the Order.  Ordering  Company shall notify Supplier
promptly of any claim with respect to loss which  occurs while  Supplier has the
risk of loss and shall  cooperate  in every  reasonable  way to  facilitate  the
settlement of any claim.

                                   ARTICLE III
                               PRICES AND PAYMENT

                  3.1  PRICES.  (a) To the extent  Ordering  Company's  Order is
subject to a firm price  quotation made by Supplier,  prices,  fees, and charges
("Prices")  shall be as set  forth in  Supplier's  firm  price  quotation  or as
specified in the governing  Supplemental  Agreement.  In all other cases, Prices
shall be as set  forth in the  Product  Information  Catalog  Extraction  System
("PRICES")  which  provides  toll free  access to  Supplier's  complete  Product
listing or in ELIB (electronic  library  information  bulletin) or its successor
and will be provided in  electronic  media.  For firm price  quotations,  Prices
shall be valid for thirty (30) days from the date of the quotation. Prices shall
be applied based upon the date Supplier receives Ordering  Company's Order. Both
parties  will work  together in the first  quarter of 1996 to develop a plan for
the migration to PRICES.

                  (b) The  database for pricing of all  Standard
Service  Units
("SSU's") Products and Services is Service Unit Dictionary System
("SUDS").

                  (c)  Where  Supplier  is  not  performing  installation,   all
expenses after shipment from Supplier's  manufacturing or software  distribution
facility  shall  be paid by  Ordering  Company.  If  Supplier  pays  any of such
expenses, they shall be borne by Ordering Company plus






a fifteen  percent  (15%)  administration  fee.  Supplier  will not  incur  such
expenses  unless it is requested to do so in writing by Ordering  Company (which
request shall constitute  Ordering Company's  agreement to pay Supplier for such
expenses).

                  (d) Notwithstanding the foregoing, if Supplier is delayed from
completion of an Order due to any change  requested by Ordering  Company or as a
result of delay by Ordering  Company in furnishing  information or in performing
its obligations  (including site preparation),  Supplier's prices are subject to
change to the extent that Supplier incurs costs for such delay.

                  (e) Unless expressly stated in writing,  Supplier's prices are
exclusive of charges for  transportation  and other  related  Services,  and any
sales or other tax or duty which Supplier may be required to collect or pay upon
the ordered transaction. Supplier shall include these items as separate items in
its invoiced prices to Ordering  Company.  Ordering Company shall be responsible
for prepaid  transportation  paid by Supplier.  Billable premium  transportation
will be used only with Ordering Company's concurrence.

                  (f)  Supplier may amend its pricing  schedules  once every six
(6) months by  providing  sixty  (60) days'  prior  written  notice.  Unless the
parties agree otherwise in writing,  Supplier's unaccepted firm price quotations
may be amended on ten (10) days'  written  notice.  Such  changes in  Supplier's
pricing shall apply only to Orders  received on or after the  effective  date of
such price changes.

                  (g) In addition to the applicable Price,  reasonable  expenses
for  travel  and  living of  Supplier's  personnel  while on travel  assignments
outside the local area,  approved by Ordering  Company,  shall be  reimbursable.
Such  approval may be written or oral and on an  individual  case basis or for a
category of such  assignments.  If oral approval is given,  it shall be followed
with a written  approval in ten (10) days.  Supplier  shall submit  invoices for
reimbursable  travel and living expenses  promptly upon completion of the travel
events.  Supplier  shall list the travel and living charges as separate items on
each invoice. Supplier shall retain all records in accordance with IRS standards
of such  charges for a period of not less than one (1)  calendar  year after the
expiration of the travel  assignment.  Upon reasonable request in the event of a
question,  Supplier shall make such records available for inspection by Ordering
Company.

                  3.2 INVOICES AND TERMS OF PAYMENT.

                  (a) FOR  CALENDAR  YEAR  1996.  Invoices  and terms of payment
shall be  mutually  agreed to by both  parties no later than March 1, 1996.  The
intent is that both  parties  will plan a  movement  toward the terms of Section
3.2(b),  INVOICES  AND TERMS OF  PAYMENT,  and away from the  current  practice,
NS/NSD  Payment and Invoicing  Policy dated January 30, 1995. The principles for
1996 which the parties will strive to meet will  include (i) the  provision of a
single bill per order on last  shipment;  (ii) such bill shall not be  submitted
manually;   (iii)  billing  upon  shipment  for  Products,   Licensed  Materials
(including  transportation  charges and taxes, if applicable)  and  Engineering,
except engineering Services associated with






outside plant  construction;  (iv) billing for  Installation  upon  Installation
Complete Date; and (v) implementation on or before April 1, 1996.

                  (b) AFTER 1996.

                   (i) Products,  Licensed Materials  (including  transportation
charges and taxes, if applicable),  and Engineering Services, except engineering
Services associated with outside plant construction, shall be billed by Supplier
when last shipment on an Order is made, or as soon thereafter as practical;

                           (ii) Installation shall be billed upon
Acceptance;

                           (iii) Engineering Services associated
with outside
plant construction shall be billed as performed or, at Supplier's
discretion, on
a monthly basis;

                           (iv) Consulting, design, outside plant
construction,
system integration and program management  Services shall be billed, as mutually
agreed to by the parties (1) on a progress  basis based on the percentage of job
completed up to  eighty-five  percent of the charge or, (2) on a monthly  basis.
Final billing for such Services will be invoiced when such Service is completed;

                           (v) Unless otherwise agreed to,
Maintenance Services
shall be billed monthly, in advance. Supplier will work with Ordering Company to
minimize  the  number of bills  Ordering  Company  receives  each month for such
Services.  If Ordering  Company  requests  quarterly or annual  invoicing,  such
invoicing shall be rendered in advance of such Services;

                  (vi) Payment for generally available Licensed
Material is payable in full upon delivery to First Field
Application; and

                           (vii) Software and/or other technology
development
for  small  projects  (i.e.  less  than or  equal  to  fifteen  million  dollars
($15,000,000)  and less than or equal to twelve (12) months)  shall be billed as
follows:  ten percent (10%) at  commitment  (i.e.,  signing of contract),  forty
percent (40%) upon delivery of the Software to the  Integrated  Test Network (if
the Software  will not be tested in the ITN,  this forty  percent  (40%) payment
shall be due upon  delivery to the First Field  Application),  and fifty percent
(50%)  when  Software  is ready  for  deployment,  or  thirty  (30)  days  after
Acceptance  of the  Software in the First Field  Application,  whichever  occurs
sooner.  Billing for Software and/or other  technology  development for projects
other  than  small  projects  as defined  in the  preceding  sentence,  shall be
determined  on a case by case basis.  The parties will conform the  Supplemental
Agreements to this Section 3.4(b)(vii) by March 31, 1996.

                  (c) Ordering Company shall pay such invoiced amounts, less any
items known then to be disputed  items,  within  thirty (30) days of the date of
Supplier's  invoice.  Ordering  Company  shall  notify  Supplier of any disputed
invoice within eighteen (18) months from the date of the invoice. Such notice of
dispute shall not excuse Ordering Company from






timely payment of the undisputed portion(s) of any invoice containing a disputed
portion.  Supplier may apply any credit which  remains  outstanding  in favor of
Ordering  Company to the oldest  undisputed  invoice  which  remains in Ordering
Company's account, unless directed otherwise by Ordering Company.

                  (d) Unless otherwise agreed,  payment of all amounts contained
in this  Agreement  shall be made in United States dollars and invoices shall be
rendered  in the same  currency.  Unless  otherwise  agreed to by  Supplier  and
Ordering Company,  payments shall be made by electronic  transfer to the account
and address  indicated by Supplier and shall  reference the  invoice(s) to which
they relate.

                  (e) AT&T  guarantees  payment in United States  dollars of the
obligations of Ordering  Companies that are not Affiliates of AT&T on any Orders
placed pursuant to this  Agreement.  Payment shall be made by AT&T within thirty
(30) days after  receipt of invoice of a guaranteed  payment.  Such invoice will
only be issued to AT&T  after  Supplier  has made  reasonable  efforts to obtain
payment from Ordering  Company.  Ordering  Companies that are Affiliates of AT&T
shall  bear  sole  responsibility  for  the  performance  of  their  obligations
hereunder.

                  3.3 TAXES. (a) Ordering Company shall bear all taxes,  levies,
duties and other  similar  charges  (and any related  interest  and  penalties),
however  designated,  (herein  referred to as "Tax")  imposed as a result of the
existence or operation of this Agreement,  Order or any Supplemental  Agreement,
including  but not  limited to any tax which  Ordering  Company is  required  to
withhold,  collect  or deduct  from  payments  to  Supplier,  except (i) any tax
imposed upon Supplier in a jurisdiction outside the United States if such tax is
allowable as a credit  against the United States  income taxes of Supplier;  and
(ii) any net income  tax  imposed  upon  Supplier  by the  United  States or any
governmental  entity  within the United States proper (the fifty (50) states and
the District of Columbia including, but not limited to counties,  municipalities
and other  localities).  In order for the  exception  contained in (i) to apply,
Ordering  Company must furnish Supplier with such evidence as may be required by
United States taxing  authorities  to establish  that such Tax has been paid, if
any, so Supplier may claim the credit.

                  (b) If Ordering  Company is required to bear a tax pursuant to
paragraph (a) above,  Ordering  Company shall pay to Supplier or the appropriate
government  entity  or taxing  authority,  such Tax and  other  charges  and any
additional  amounts as are necessary to ensure that the net amounts  received by
Supplier  after all such  payments  or  withholdings  equal the amounts to which
Supplier is  otherwise  entitled  under this  Agreement  as if such Tax or other
charges did not exist.

                  (c) If  Ordering  Company  is  exempt  from any Tax,  Ordering
Company shall  provide  Supplier  with all required  documentation  necessary to
establish  Ordering  Company's exempt status.  Ordering Company hereby agrees to
indemnify  Supplier from any Tax,  including  penalties and interest,  resulting
from Supplier's reliance on Ordering Company's claim of exempt status.






                  (d)  If   Ordering   Company   disputes   in  good  faith  the
applicability  of any Tax imposed as a result of the  existence  or operation of
this Agreement,  Ordering  Company,  at its own expense and in its own name, may
contest the taxing jurisdiction of the disputed Tax. In the event the applicable
law  requires  that such  contest  must be taken in the name of  Supplier  only,
Supplier  shall in good faith and with due diligence at Ordering  Company's sole
expense  contest the  imposition of such Tax provided that (i) Supplier will not
be required to pursue such  contest if the action will result in a lien  against
Supplier for which Ordering Company has not adequately  indemnified  Supplier or
(ii) will result in a penalty being assessed against Supplier for which Ordering
Company has not adequately indemnified Supplier.


                                   ARTICLE IV
                          INTELLECTUAL PROPERTY RIGHTS

             4.1 USE OF INFORMATION.  (a) All technical and business Information
disclosed  by one  party  to the  other  subsequent  to the  execution  of  this
Agreement  in  whatever  form  recorded   which  is  marked   "proprietary"   or
"confidential"  or bears a legend or notice  restricting  its use,  copying,  or
dissemination  or, if not in tangible form, is described as being proprietary or
confidential  at the time of  disclosure  and is  subsequently  summarized  in a
writing so marked and delivered to the  receiving  party within thirty (30) days
of disclosure to the receiving party shall remain the property of the furnishing
party. Similarly,  all technical and business Information disclosed by one party
to the other party prior to the execution of this Agreement and described at the
time of disclosure by the furnishing party as being  proprietary or confidential
or known by the party receiving disclosure of such Information to be proprietary
or confidential shall remain the property of the furnishing party (regardless of
whether it is ever recorded in tangible form).

          (b) The furnishing  party grants the receiving  party the right to use
such Information  only as follows:  Such Information (i) shall not be reproduced
or copied, in whole or part, except for use as authorized in this Agreement; and
(ii) shall,  together with any full or partial  copies  thereof,  be returned or
destroyed  when  no  longer  needed.   Supplier  shall  use  Ordering  Company's
Information  only for the  purpose  of  performing  under  this  Agreement,  and
Ordering  Company shall use Supplier's  Information  only (i) to order Products,
Licensed Materials or Services;  (ii) to evaluate Supplier's Products,  Licensed
Materials or Services; or (iii) to install,  operate and maintain the particular
Products  or  Licensed  Materials  for which  such  Information  was  originally
furnished.  Unless the furnishing party consents in writing,  such  Information,
except for that part, if any, which was previously  known to the receiving party
free of any  confidential  obligation,  or which becomes  generally known to the
public  through  acts  not  attributable  to the  receiving  party,  or  which a
receiving  party  receives from a third party without  restriction,  or which is
independently  developed by the receiving party,  shall be held in confidence by
the receiving  party. The receiving party may disclose such Information to other
persons, upon the furnishing party's prior written authorization,  but solely to
perform  acts which this clause  expressly  authorizes  the  receiving  party to
perform itself and further provided that






such other person agrees in writing (a copy of which writing will be provided to
the furnishing  party at its request) to the same  conditions  respecting use of
Information  contained  in this  clause and to any other  reasonable  conditions
requested  by  the  furnishing   party.  The  contents  of  this  Agreement  are
confidential  and  shall not be  disclosed  by  either  party to third  parties,
without the prior written agreement of both parties hereto, except to the extent
required  by  applicable  law,  a  court  or  regulatory   agency  of  competent
jurisdiction.

                  (c) Each  party  shall be  liable  to the  other  for  damages
resulting  from  violation of this Section 4.1. Those damages shall be unlimited
as to nature and limited as to amount to thirty  million  dollars  ($30,000,000)
per occurrence.

                  4.2 INFRINGEMENT AND MISAPPROPRIATION. (a) In the event of any
claim,  action,  proceeding  or suit by a third party against  Ordering  Company
alleging an infringement of any patent, copyright, trademark or misappropriation
of a trade secret  recognized in any jurisdiction  where an Ordering Company may
lawfully use or operate Products or Licensed Materials purchased  hereunder,  or
if by reason of the use, in accordance  with Supplier's  Specifications,  in any
such jurisdiction of any Products or Licensed Materials furnished by Supplier to
an Ordering Company under this Agreement, Supplier, at its expense, shall defend
Ordering Company,  subject to the conditions and exceptions stated in Paragraphs
(b), (c), (d), and (e) below.  Supplier shall reimburse Ordering Company for all
costs,  expenses or attorneys'  fees incurred at Supplier's  written  request or
authorization,  and shall  indemnify  Ordering  Company  against  any  liability
assessed  against  Ordering  Company  by  final  judgment  on  account  of  such
infringement or violation arising out of such use. In no event shall Supplier be
liable for Ordering Company's consequential damages.

                  (b) If Ordering  Company's  use is  enjoined or in  Supplier's
opinion  is  likely to be  enjoined,  Supplier  shall,  at its  expense  use its
reasonable best efforts,  to either (i) replace the enjoined Product or Licensed
Materials  furnished  pursuant to this Agreement  with a substitute  free of any
infringement;  (ii)  modify it so that it will be free of the  infringement;  or
(iii)  procure for Ordering  Company a license or other right to use it. If none
of the foregoing options is achievable through reasonable best efforts, Supplier
shall remove the enjoined Product or Licensed  Materials and refund or credit to
Ordering Company any amounts paid to Supplier  therefor less a reasonable charge
for depreciation and any actual period of use by Ordering Company.  In no event,
however,  shall  Supplier's  liability  under  this  Section  4.2(b)  exceed the
amount(s)  paid by Ordering  Company to  Supplier to purchase  the Product or to
obtain the right to use the Licensed  Materials which are alleged to violate the
rights described in Paragraph (a) above.

                  (c) Ordering Company shall give Supplier prompt written notice
of all such claims,  actions,  proceedings  or suits  alleging  infringement  or
violation and Supplier shall have full and complete authority to assume the sole
defense thereof,  including appeals, and to settle same. Ordering Company shall,
upon Supplier's request and at Supplier's  expense,  furnish all information and
assistance  available to Ordering  Company and cooperate in every reasonable way
to  facilitate  the  defense  and/or  settlement  of  any  such  claim,  action,
proceeding or suit.






                  (d) No  undertaking of Supplier under this clause shall extend
to any such alleged  infringement or violation to the extent that it: (i) solely
arises from  adherence to design  modifications,  Specifications,  drawings,  or
written  instructions  which Supplier is directed by Ordering  Company to follow
but only if such alleged  infringement  or  misappropriation  does not reside in
material  of  Supplier's  origin,  design  or  selection;  or (ii)  arises  from
adherence to instructions to apply Ordering Company's  trademark,  trade name or
other company identification; or (iii) resides in equipment or Software which is
furnished by Ordering Company to Supplier for use under this Agreement;  or (iv)
arises  from use of the Product or  Licensed  Materials  provided by Supplier in
combination  with any item not furnished  directly by Supplier;  or (v) is based
upon modification made by Ordering Company of any Product or Licensed Materials;
or (vi)  arises  from use of any  Product or  Licensed  Material in a manner for
which it was not  designed.  In the foregoing  cases  numbered (i) through (vi),
Ordering  Company shall defend and save Supplier  harmless,  subject to the same
terms and  conditions and  exceptions  stated above,  with respect to Supplier's
rights and obligations under this clause.

                  (e) The liability of Supplier,  AT&T and Ordering Company with
respect to any and all claims,  actions,  proceedings  or suits by third parties
alleging infringement of patents, trademarks or copyrights or violation of trade
secrets or proprietary rights because of, or in connection with, any Products or
Licensed Materials  furnished pursuant to this Agreement shall be limited to the
specific undertakings contained in this Section 4.2.

                  4.3 NO PATENT  LICENSES.  Nothing  contained  herein  shall be
construed as  conferring  by  implication,  estoppel or otherwise any license or
right  under  any  patent,  except  that  which is  essential  to the use of the
Products and/or Licensed Materials as provided by Supplier, and provided however
that  this  Section  4.3  shall  not  limit  or  modify  any of the  rights  and
obligations of the Intellectual  Property Agreements or the Supplemental General
Purchase  Agreement,  No.  LC3757D,  both  executed as of this date as Ancillary
Agreements to the Separation and Distribution  Agreement.  Supplier shall retain
all ownership rights in all intellectual property used or embodied in Supplier's
Products,  Licensed Materials and Service unless otherwise  expressed herein, or
in a Supplemental Agreement.

                  4.4  TRADEMARKS.  (a) Subject to the  provisions  of the Brand
License  Agreement,  executed as of this date as an  Ancillary  Agreement to the
Separation and  Distribution  Agreement,  each party shall have the right to use
Products and Licensed Materials which bear the other party's  trademarks,  trade
name, logos, trade devices,  service marks, symbols, and codes, unless otherwise
directed by that party to remove such indicia.

                  (b) Except as provided in Section s 4.4 (a) above,  each party
(including  in the  case  of  AT&T,  each  Ordering  Company)  shall  not use in
advertising or otherwise,  any of the other party's trade name, logo, trademark,
trade device, service mark, symbol, code or Specification,  or any abbreviation,
contraction,  or simulation  thereof,  without the prior written consent of such
party. Neither party shall claim any ownership therein, and any such usage shall
inure to the benefit of the party which owns such trade name, logo, trademark,



trade device, service mark, symbol, code or Specification.






                  4.5 PROPRIETARY  NOTICE.  Ordering Company shall reproduce and
include any Supplier copyright or proprietary notice on all authorized copies of
Licensed  Materials.  Ordering Company shall also mark all media containing such
copies with a warning that the Licensed  Materials  are subject to  restrictions
contained  in an  agreement  between  Supplier  and AT&T and that such  Licensed
Material are the property of Supplier.

                                 RISK MANAGEMENT

5.1 ORDERING COMPANIES' REMEDIES.

         (a) An Ordering  Company's  exclusive remedies and the entire liability
of Supplier,  Supplier's  Affiliates and their  employees and agents,  and their
vendors for any claim,  loss, damage or expense of Ordering Company or any other
entity arising out of this Agreement or any Supplemental  Agreement,  or the use
or performance of any Product,  Licensed Materials,  or Services,  whether in an
action for or  arising  out of breach of  contract,  warranty,  tort,  including
negligence, or strict liability, shall be as follows:

                           (i) For infringement -- the remedy set
forth above in
Section 4.2, INFRINGEMENT AND MISAPPROPRIATION;

                 (iii)  For  the  performance  or  nonperformance  of  Products,
Software,  and  Services or claims  that they do not conform to a  warranty--the
remedy shall include those set forth in the applicable "warranty" clause;

                           (iv) For third party claims against
Ordering Company
for personal injury and property damage for which Supplier is held
liable -- the
remedy afforded by the governing law;

                           (v) For tangible property damage to
Ordering Company
caused by Supplier's negligence -- the amount of the direct
damages; and

                           (vi) For Supplier's failure to deliver
Products,
Licensed  Materials  or Services  on  Supplier's  scheduled  delivery  date,  if
Supplier fails to deliver such Products,  Licensed Materials or Services (aa) in
1996 within  forty-five  (45) days from receipt of written  notice from Ordering
Company to Supplier of its failure to deliver such Products,  Licensed Materials
or Services on Supplier's  scheduled  delivery date and (ab)  thereafter  thirty
(30) days from receipt of such notice, the following remedies shall apply:






                                    (A) Ordering Company may
cancel the Order
without incursion of cancellation fees; and,

                                    (B) Ordering Company may
request and
Supplier will reduce AT&T's volume purchase commitment by an amount equal to the
value of the Order. In addition, if a worldwide supply shortage exists, Ordering
Company may request and, upon such request, shall receive priority on allocation
of such  delivered  Products,  Licensed  Materials  or  Services  in a  shortage
condition  based  upon  priority  criteria  agreed to between  Supplier  and its
affected customers established for the particular shortage condition.

                  (b)  Notwithstanding any other provision of this
Agreement and
except as provided in Section 5.1(a)(ii) above,  ORDERING
COMPANIES'  REMEDIES,
Supplier,  Supplier's  Affiliates  and their  employees  and  agents,  and their
vendors shall not be liable for any consequential  damages in the nature of lost
profits,  revenues  or  savings  arising  out of this  Agreement,  or the use or
performance  of any Product,  Licensed  Materials,  or  Services,  whether in an
action for or  arising  out of breach of  contract,  warranty,  tort,  including
negligence, or strict liability.

                  (c) Other than damages pursuant to Section  5.1(a)(ii)  above,
ORDERING COMPANIES'  REMEDIES,  Supplier's total liability for incidental and/or
consequential  damages and damages  resulting from network outages which must be
reported  by  Ordering  Company  to the  Federal  Communications  Commission  in
accordance  with its rules  ("Network  Outage(s)")  shall not exceed ten million
dollars  ($10,000,000)  per  occurrence  with a total  not to  exceed  of thirty
million dollars ($30,000,000) in any one year. This Section 5.1(c) shall survive
failure of an exclusive or limited remedy.

                  (d) Ordering Company shall give Supplier prompt written notice
of any claim.  Any action or proceeding  against Supplier must be brought within
thirty-six (36) months after the cause of action accrues.


                  (e)  Supplier  acknowledges  that a Network  Outage will cause
damage to AT&T in an amount  impossible  to  ascertain.  Supplier  agrees to pay
AT&T, as liquidated damages and not as a penalty, the sum of one million dollars
($1,000,000)  per  occurrence in the event of a Network  Outage caused solely by
Supplier in  connection  with network  infrastructure  equipment and one hundred
thousand  dollars  ($100,000)  per  occurrence in the event of a Network  Outage
caused  solely by Supplier in connection  with BCS  Products,  whether or not by
breach of warranty and whether before, during or after any Warranty Period. With
respect to a Network Outage caused solely by Supplier in connection with network
infrastructure  equipment,  Supplier's  total  liability for damages for Network
Outages,  including the liquidated damages described herein shall be one million
dollars  ($1,000,000)  per  occurrence not to exceed the amount of three million
dollars  ($3,000,000)  for any calendar year, and Supplier's total liability for
damages  for Network  Outages  for any three (3) year period of this  Agreement,
including the liquidated damages described herein, shall be five million dollars
($5,000,000); provided that AT&T is meeting its obligations specified in Section
1A.3, VOLUME COMMITMENT, and the








Pricing Agreement.  With respect to Network Outages caused solely by Supplier in
connection  with BCS Products,  Supplier's  total  liability  under this section
shall be one hundred  thousand  dollars  ($100,000) per occurrence not to exceed
the amount of three hundred  thousand  dollars  ($300,000) for any calendar year
,and  Supplier's  total  liability for damages for Network Outages for any three
(3) year period of this Agreement,  including the liquidated  damages  described
herein, shall be five hundred thousand dollars ($500,000); provided that AT&T is
meeting its obligations  specified in Section 1A.3, VOLUME  COMMITMENT,  and the
Pricing Agreement. If, at any time during the term of this Agreement, AT&T fails
to meet its obligations  specified in Section 1A.3, VOLUME  COMMITMENT,  and the
Pricing  Agreement,  it shall not be  entitled  to the  remedy  in this  Section
5.1(e).  Any damages  paid by Supplier  pursuant to this  Subparagraph  shall be
considered  incidental and  consequential  damages subject to the limitations on
AT&T's  right to  recover  same that are set forth in Section  5.1(c),  ORDERING
COMPANIES' REMEDIES.  At AT&T's option, AT&T may take all or part of the payment
as a credit  against any invoice due or to become due to Supplier.  The remedies
available  to AT&T under  Section 5.1,  ORDERING  COMPANIES'  REMEDIES,  and the
foregoing  liquidated  damages shall constitute AT&T's sole and exclusive remedy
for Network  Outages  caused to any extent by  Supplier  during the term of this
Agreement.

                  5.2  SUPPLIER  PERFORMANCE.  AT&T and  Supplier  will  jointly
develop  requirements for an annual Supplier Merit Award by December 1st of each
year for the following  year. For 1996, the  requirements  are listed in Exhibit
5-1. The award  program will  provide that if Supplier  meets or exceeds  either
award performance criteria for receipt of a Supplier Merit Award, AT&T shall:

                           (a) increase its minimum volume
purchase commitment
for the  following  year (if the volume  purchase  commitment  in Section  1A.3,
VOLUME COMMITMENT,  is in effect),  by twenty million dollars  ($20,000,000) for
achieving the on-time delivery criteria and ten million dollars
($10,000,000)
for achieving the FCC reportable incidents criteria or

                           (b) if a volume purchase commitment is
not in effect,
increase its purchase or license of Supplier's Products,  Licensed Materials and
Services for the following  year by twenty  million  dollars  ($20,000,000)  for
achieving the on-time delivery criteria and ten million dollars
($10,000,000)
for achieving the FCC reportable  incidents criteria. A public relations program
will be jointly developed and executed in support of this award program.

                  5.3 INSURANCE.  Supplier  shall maintain and cause  Supplier's
subcontractors  to  maintain  during the term of this  Agreement:  (a)  Workers'
Compensation  insurance as prescribed by the law of the state or nation in which
the work is performed,  (b)  employer's  liability  insurance  with limits of at
least  three  hundred  thousand  dollars  ($300,000)  for each  occurrence;  (c)
comprehensive  automobile  liability  insurance if the use of motor  vehicles is
required,  with limits of at least one  million  dollars  ($1,000,000)  combined
single limit for bodily  injury and  property  damage for each  occurrence,  (d)
Comprehensive General Liability ("CGL") insurance, including Blanket Contractual
Liability and Broad Form Property damage, with limits of at least








one million dollars  ($1,000,000)  combined single limit for personal injury and
property  damage for each  occurrence;  and (e) if the  furnishing  to  Ordering
Company  (by sale or  otherwise)  of  Products  or  material  is  involved,  CGL
insurance  endorsed  to include  products  liability  and  completed  operations
coverage in the amount of five million dollars ($5,000,000) for each occurrence.
If specifically requested by Ordering Company,  Supplier's  subcontractors shall
furnish,  prior to the  start of work,  certificates  or  adequate  proof of the
foregoing  insurance,   including  copies  of  the  endorsements  and  insurance
policies.  Supplier's  obligations  to maintain  insurance  may be  satisfied by
providing proof of self-insurance in a form satisfactory to Company.

                         ARBITRATION; DISPUTE RESOLUTION

                  5A.1 AGREEMENT TO ARBITRATE.  The  procedures for  discussion,
negotiation  and  arbitration  set forth in this  Article 5A shall  apply to all
disputes,  controversies  or  claims  (whether  sounding  in  contract,  tort or
otherwise)  that may arise out of or related to, or arise under or in connection
with  this  Agreement  or  any  Supplemental   Agreement,  or  the  transactions
contemplated  hereby or thereby  (including  all actions taken in furtherance of
the transactions contemplated hereby or thereby on or prior to the date hereof),
or the  commercial  or economic  relationship  of the parties  relating  hereto,
between the  parties.  Each party agrees that the  procedures  set forth in this
Article  5A shall  be the  sole and  exclusive  remedy  in  connection  with any
dispute,  controversy  or claim  relating  to any of the  foregoing  matters and
irrevocably   waives  any  right  to  commence  any  Action  in  or  before  any
Governmental Authority except as expressly provided in Section 5A.7(b),  CERTAIN
ADDITIONAL  MATTERS,  and 5A.8,  LIMITED COURT ACTIONS,  below and except to the
extent  provided  under the  Arbitration  Act in the case of judicial  review of
arbitration results or awards. Each party on behalf of itself irrevocably waives
any right to any trial by jury with respect to any such claim,  controversy,  or
dispute.









                  5A.2  ESCALATION.  (a) It is the intent of the  parties to use
their respective  reasonable best efforts to resolve  expeditiously any dispute,
controversy  or claim between or among them with respect to the matters  covered
hereby  that may arise  from time to time on a  mutually  acceptable  negotiated
basis.  In  furtherance  of the  foregoing,  any party  involved  in a  dispute,
controversy or claim may deliver a notice (an "Escalation  Notice") demanding an
in person meeting involving  representatives of the parties at a senior level of
management of the parties (or if the parties agree, of the appropriate strategic
business  unit or division  within such entity).  A copy of any such  Escalation
Notice shall be given to the General  Counsel,  or like officer or official,  of
each party involved in the dispute, controversy or claim (which copy shall state
that it is an  Escalation  Notice  pursuant  to  this  Agreement).  Any  agenda,
location or procedures for such discussions or negotiations  between the parties
may be established by the parties from time to time; provided, however, that the
parties shall use their  reasonable best efforts to meet within thirty (30) days
of the Escalation Notice.

                  (b) The parties may, by mutual  consent,  retain a mediator to
aid the parties in their  discussions and  negotiations by informally  providing
advice to the parties.  Any opinion  expressed by the mediator shall be strictly
advisory  and shall  not be  binding  on the  parties,  nor  shall  any  opinion
expressed by the mediator be  admissible  in any  arbitration  proceedings.  The
mediator  may be chosen  from a list of  mediators  previously  selected  by the
parties or by other  agreement of the parties.  Costs of the mediation  shall be
borne  equally by the parties  involved  in the  matter,  except that each party
shall be responsible for its own expenses.  Mediation is not a prerequisite to a
demand for arbitration under Section 5A.3, DEMAND FOR ARBITRATION.
   

                 5A.3.  DEMAND FOR ARBITRATION.  (a) At any time after the first
to occur of (i) the date of the meeting actually held pursuant to the applicable
Escalation  Notice  or (ii)  forty  five  (45) days  after  the  delivery  of an
Escalation  Notice (as applicable,  the  "Arbitration  Demand Date"),  any party
involved in the dispute,  controversy or claim (regardless of whether such party
delivered  the  Escalation  Notice)  may,  unless the  applicable  deadline  has
occurred,  make a written  demand (the  "Arbitration  Demand  Notice")  that the
dispute be resolved by binding  arbitration,  which  Arbitration  Demand  Notice
shall be given in the  manner set forth in Section  6.3,  NOTICES.  In the event
that any party shall deliver an Arbitration Demand Notice to another party, such
other party may itself deliver an Arbitration  Demand Notice to such first party
with respect to any related dispute,  controversy or claim with respect to which
the applicable  deadline has not passed without the requirement of delivering an
Escalation  Notice.  No party may assert  that the failure to resolve any matter
during  any  discussions  or  negotiation,  the  course of  conduct  during  the
discussions  or  negotiations  or the failure to agree on a mutually  acceptable
time,  agenda,  location  or  procedures  for  the  meeting,  in each  case,  as
contemplated  by  Section  5A.2,  ESCALATION,  is  prerequisite  to a demand for
arbitration  under this Section  5A.3.  In the event that any party  delivers an
Arbitration Demand Notice with respect to any dispute, controversy or claim that
is the subject of any then  pending  arbitration  proceeding  or of a previously
delivered Arbitration Demand Notice, all such disputes, controversies and claims
shall be resolved in the arbitration  proceeding for which an Arbitration Demand
Notice was first delivered unless the








arbitrator in his or her sole discretion determines that it is
impracticable or
otherwise inadvisable to do so.

                  (b) Any Arbitration  Demand Notice may be given until one year
and forty five (45) days after the later of the  occurrence  of the act or event
in the exercise of reasonable due diligence  giving rise to the underlying claim
or the date on which such act or event was, or should have been,  discovered  by
the party asserting the claim (as applicable, and as it may in a particular case
be specifically extended by the parties in writing, the "Applicable  Deadline").
Any discussions, negotiations or mediations between the parties pursuant to this
Agreement or otherwise will not toll the Applicable  Deadline  unless  expressly
agreed  in  writing  by the  parties.  Each  of the  parties  agrees  that if an
Arbitration Demand Notice with respect to a dispute, controversy or claim is not
given prior to the  expiration of the Applicable  Deadline,  as between or among
the  parties,  such  dispute,  controversy  or claim will be barred.  Subject to
Section 5A.7 (d), CERTAIN ADDITIONAL  MATTERS,  and 5A.8, LIMITED COURT ACTIONS,
upon delivery of an  Arbitration  Demand  Notice  pursuant to Section 5A.3 (b) ,
DEMAND  FOR  ARBITRATION,   prior  to  the  Applicable  Deadline,  the  dispute,
controversy  or claim shall be decided by a sole  arbitrator in accordance  with
the rules set forth in this Article 5A.

                  5A.4. ARBITRATORS. (a) Within fifteen (15) days
after a valid
Arbitration Demand Notice is given, the parties involved in the
dispute,
controversy or claim referenced therein shall attempt to select a
sole
arbitrator satisfactory to all such parties.

                  (b) In the event  that such  parties  are not able to  jointly
select a sole arbitrator within such fifteen (15) day period, such parties shall
each appoint an arbitrator (who need not be  disinterested  as to the parties or
the matter)  within thirty (30) days after  delivery of the  Arbitration  Demand
Notice.  If one party  appoints  an  arbitrator  within such time period and the
other party or parties  fail to appoint an  arbitrator  within such time period,
the  arbitrator  appointed by the one party shall be the sole  arbitrator of the
matter.

                  (c)  In the  event  that a  sole  arbitrator  is not  selected
pursuant  to  paragraph  (a) or (b)  above  and,  instead,  two (2) or three (3)
arbitrators  are  selected  pursuant to  paragraph  (b) above,  the two or three
arbitrators  will, within thirty (30) days after the appointment of the later of
them to be appointed,  select an additional arbitrator who shall act as the sole
arbitrator of the dispute. After selection of such sole arbitrator,  the initial
arbitrators shall have no further role with respect to the dispute. In the event
that the  arbitrators  so  appointed do not,  within  thirty (30) days after the
appointment of the later of them to be appointed,  agree on the selection of the
sole arbitrator,  any party involved in such dispute may apply to CPR, New York,
New York, to select the sole  arbitrator,  which selection shall be made by such
organization  within  thirty (30) days after such  application.  Any  arbitrator
selected  pursuant to this paragraph (c) shall be disinterested  with respect to
any of the  parties  and the matter  and shall be  reasonably  competent  in the
applicable subject matter.

                  (d) The sole  arbitrator  selected  pursuant to paragraph (a),
(b) or (c)  above  will set a time for the  hearing  of the  matter  which  will
commence no later than ninety (90) days after the










date of appointment of the sole arbitrator pursuant to paragraph (a), (b) or (c)
above,  and which hearing will be no longer than thirty (30) days (unless in the
judgment of the arbitrator the matter is unusually complex and sophisticated and
thereby  requires a longer time,  in which event such hearing shall be no longer
than ninety (90) days).  The final decision of such  arbitrator will be rendered
in writing to the parties not later than sixty (60) days after the last  hearing
date, unless otherwise agreed by the parties in writing.

                  (e) The place of any arbitration hereunder will
be New Jersey,
unless otherwise agreed by the parties.

                  5A.5  HEARINGS.  Within the time period  specified  in Section
5A.4 (d),  ARBITRATORS,  the matter shall be presented  to the  arbitrator  at a
hearing  by means of written  submissions  of  memoranda  and  verified  witness
statements, filed simultaneously, and responses, if necessary in the judgment of
the arbitrator or both parties.  If the arbitrator deems it to be essential to a
fair resolution of the dispute, live cross-examination or direct examination may
be permitted,  but is not generally contemplated to be necessary. The arbitrator
shall actively  manage the arbitration  with a view to achieving a just,  speedy
and  cost-effective  resolution  of  the  dispute,  claim  or  controversy.  The
arbitrator may, in his discretion, set time and other limits on the presentation
of each party's case, its memoranda or other submissions,  and refuse to receive
any proffered  evidence,  which the arbitrator,  in his discretion,  finds to be
cumulative,  unnecessary,  irrelevant  or of low  probative  nature.  Except  as
otherwise  set forth  herein,  any  arbitration  hereunder  will be conducted in
accordance  with the CPR  Rules for  Non-Administered  Arbitration  of  Business
Disputes  (except  that the fee  schedule of the CPR will not apply).  Except as
expressly set forth in Section 5A.8(b),  LIMITED COURT ACTIONS,  the decision of
the arbitrator  will be final and binding on the parties,  and judgment  therein
may be had and will be  enforceable  in any court having  jurisdiction  over the
parties.  Arbitration  awards will bear  interest at an annual rate of the Prime
Rate Plus two percent (2%) per annum.  To the extent that the provisions of this
Agreement and the prevailing  rules of the CPR conflict,  the provisions of this
Agreement shall govern.


                  5A.6  DISCOVERY  AND  CERTAIN  OTHER  MATTERS.  (a) Any  party
involved in the applicable dispute may request limited document  production from
the other party or parties of specific and expressly  relevant  documents,  with
the reasonable  expenses of the producing party incurred in such production paid
by the requesting  party. Any such discovery (which rights to documents shall be
substantially  less than document  discovery rights prevailing under the Federal
Rules of Civil Procedure) shall be conducted  expeditiously  and shall not cause
the hearing provided for in Section 5A.5, HEARINGS,  to be adjourned except upon
consent  of  all  parties  involved  in  the  applicable   dispute  or  upon  an
extraordinary  showing of cause demonstrating that such adjournment is necessary
to  permit  discovery  essential  to a  party  to the  proceeding.  Depositions,
interrogatories or other forms of discovery (other than the document  production
set forth above) shall not occur except with the consent of the parties involved
in the applicable dispute.  Disputes concerning the scope of document production
and  enforcement  of the document  production  requests  will be  determined  by
written agreement of the parties








involved in the applicable dispute or, failing such agreement,  will be referred
to the arbitrator for resolution.  All discovery requests will be subject to the
parties'  rights to claim any applicable  privilege.  The arbitrator  will adopt
procedures to protect such rights and to maintain the confidential  treatment of
the arbitration  proceedings  (except as may be required by law). Subject to the
foregoing,  the arbitrator shall have the power to issue subpoenas to compel the
production of documents relevant to the dispute, controversy or claim.     
                  (b) Except where  contrary to the provisions set forth in this
Agreement or any  Supplemental  Agreement,  the rules of the CPR for  commercial
arbitration  will be applied to all matters of procedure,  including  discovery.
The  arbitrator  shall  have full power and  authority  to  determine  issues of
arbitrability  but shall  otherwise be limited to interpreting or continuing the
applicable  provisions of this  Agreement and will have no authority or power to
limit,  expand,  alter,  amend,  modify,  revoke or  suspend  any  condition  or
provision of the Agreement;  it being understood,  however,  the arbitrator will
have full  authority to  implement  the  provisions  of this  Agreement,  and to
fashion appropriate  remedies for breaches of this Agreement  (including,  other
than in the case of disputes,  controversies  or claims relating to, arising out
of or  resulting  from  Patents  (as such term is defined in the Patent  License
Agreement),   interim  or  permanent  injunctive  relief);   provided  that  the
arbitrator  shall not have (i) any  authority in excess of the authority a court
having  jurisdiction  over the parties and the controversy or dispute would have
absent these arbitration provisions or (ii) any right or power to award punitive
damages.  It is the  intention of the parties that in rendering a decision,  the
arbitrator give effect to the applicable provisions of this agreement and follow
applicable law (it being understood and agreed that this sentence shall not give
rise to a right of judicial review of the arbitrator's award).

                  (c) If a party  fails or refuses to appear at and  participate
in an  arbitration  hearing  after  due  notice,  the  arbitrator  may  hear and
determine the controversy upon evidence produced by the appearing party.

                  (d)  Arbitration  costs  will be borne  equally  by each party
involved in the matter,  except that each party will be responsible  for its own
attorneys  fees and other  costs,  expenses,  including  the costs of  witnesses
selected by such party.

                  5A.7.  CERTAIN ADDITIONAL  MATTERS.  (a) Any arbitration award
shall be a bare award  limited to a holding  for or against a party and shall be
without  findings as to facts,  issues or  conclusions  of law  (including  with
respect to any matters  relating to the validity or infringement of Patents) and
shall be without a statement of the reasoning on which the award rests, but must
be in  adequate  form so that a judgment  of a court may be  entered  thereupon.
Judgment upon any arbitration award hereunder may be entered in any court having
jurisdiction thereof.

                  (b)  Prior to the time at which  an  arbitrator  is  appointed
pursuant  to  Section  5A.4(c),  ARBITRATORS,  any  party  may  seek one or more
temporary restraining orders in a











court of  competent  jurisdiction  if necessary in order to preserve and protect
the  status  quo.  Neither  the  request  for,  nor grant or denial of, any such
temporary  restraining  order  shall be  deemed a waiver  of the  obligation  to
arbitrate  as set forth  herein and the  arbitrator  may  dissolve,  continue or
modify any such order.  Any such  temporary  restraining  order shall  remain in
effect  until the first to occur of the  expiration  of the order in  accordance
with its terms or the dissolution thereof by the arbitrator.

                  (c) Except as required by law,  the  parties  shall hold,  and
shall cause their respective officers,  directors,  employees,  agents and other
representatives  to hold,  the  existence,  content and result of  mediation  or
arbitration  in confidence in accordance  with the provisions of Section 6.2 and
except as may be  required  in order to enforce  any award.  Each of the parties
shall request that any mediator or arbitrator  comply with such  confidentiality
requirement.

                  (d) In the event  that at any time the sole  arbitrator  shall
fail to serve as an  arbitrator  for any reason,  the parties shall select a new
arbitrator  who  shall be  disinterested  as to the  parties  and the  matter in
accordance with the procedures set forth herein for the selection of the initial
arbitrator.  The extent,  if any, to which testimony  previously  given shall be
repeated  or as to  which  the  replacement  arbitrator  elects  to  rely on the
stenographic  record (if there is one) of such testimony  shall be determined by
the replacement arbitrator.


                  5A.8  LIMITED  COURT  ACTIONS.  (a)  Notwithstanding  anything
herein to the contrary,  in the event that any party  reasonably  determines the
amount of  controversy  in any dispute,  controversy  or claim (or any series of
related  disputes,  controversies  or  claims)  under this  Agreement  is, or is
reasonably likely to be, in excess of one hundred million dollars ($100,000,000)
and if such party  desires to commence an Action in lieu of  complying  with the
arbitration  provisions  of this  Article,  such  party  shall  so  state in its
Arbitration  Demand Notice or by notice given to the other parties within twenty
(20) days after receipt of an Arbitration Demand Notice with respect thereto. If
the other parties to the arbitration do not agree that the amount in controversy
in such  dispute,  controversy  or claim (or such  series of  related  disputes,
controversies  or claims)  is, or is  reasonably  likely to be, in excess of one
hundred  million dollars  ($100,000,000),  the arbitrator  selected  pursuant to
Section  5A.4,   ARBITRATORS,   hereof  shall  decide   whether  the  amount  in
controversies  or claims)  is, or is  reasonably  likely to be, in excess of one
hundred million dollars ($100,000,000).  The arbitrator shall set a date that is
no later than ten (10) days after the date of his appointment for submissions by
the parties  with  respect to such issue.  There shall not be any  discovery  in
connection  with such issue.  The  arbitrator  shall render his decision on such
issue within five (5) days of such date so set by the  arbitrator.  In the event
that the arbitrator  determines  that the amount in controversy in such dispute,
controversy  or claim (or such  series of  related  disputes,  controversies  or
claims)  is, or is  reasonably  likely to be, in excess of one  hundred  million
dollars   ($100,000,000),   the  provisions  of  Sections   5A.4(d),   and  (e),
ARBITRATORS,  5A.5, HEARINGS,  5A.6, DISCOVERY AND CERTAIN OTHER MATTERS,  5A.7,
CERTAIN ADDITIONAL  MATTERS,  and 5A.10, LAW GOVERNING  ARBITRATION  PROCEDURES,
hereof shall not apply and on or before (but,  except as expressly  set forth in
Section 5A.8(b), not after) the tenth (10th) business day after the date of












such decision,  any party to the arbitration may commence an Action with respect
to such  dispute,  controversy  or claim (or such  series of  related  disputes,
controversies  or  claims)  in  any  court  of  competent  jurisdiction.  If the
arbitrator does not so determine, the provisions of this Article (including with
respect to time periods) shall apply as if no determinations were sought or made
pursuant to this Section 5A.8.

                  (b) In the event  that an  arbitration  award in excess of one
hundred million dollars  ($100,000,000.) is issued in any arbitration proceeding
commenced  hereunder,  any party may,  within  sixty (60) days after the date of
such  award,  submit  the  dispute,  controversy  or claim (or series of related
disputes,  controversies  or claims)  giving rise  thereto a court of  competent
jurisdiction,  regardless  of whether  such party or any other  party  sought to
commence an action in lieu of proceeding  with  arbitration  in accordance  with
Section 5A.8(a).  In such event, the applicable court may, if it determines that
it would be advisable in connection  with the matter,  allow the parties to seek
additional  discovery  or to present  additional  evidence.  Each party shall be
entitled  to present  arguments  to the court with  respect to whether  any such
additional  discovery  or evidence  shall be  permitted  and with respect to all
other  matters  relating to the  applicable  dispute,  controversy  or claim (or
series of related disputes, controversies or claims).

                  (c)  No  party  shall  raise  as  a  defense  the  statute  of
limitations  if the  applicable  Arbitration  Demand  Notice was delivered on or
prior to the Applicable Deadline and, if applicable,  the matter is submitted to
a court of competent  jurisdiction within the sixty (60) day period specified in
Section 5A.8(b).

                  5A.9. CONTINUITY OF SERVICE AND PERFORMANCE.  Unless otherwise
agreed in writing,  the parties will  continue to provide  service and honor all
other commitments  under this Agreement during the course of dispute  resolution
pursuant to the  provisions  of this  Article 5A with respect to all matters not
subject to such dispute, controversy or claim.

                  5A.10.    LAW   GOVERNING    ARBITRATION    PROCEDURES.    The
interpretation of the provisions of this Article 5A, only insofar as they relate
to the  agreement to arbitrate  and any  procedures  pursuant  thereto  shall be
governed by the Arbitration Act and other  applicable  federal law. In all other
respects, the interpretation of this Agreement shall be governed as set forth in
Section 6.19, GOVERNING LAW.

                                   ARTICLE VI
                                  MISCELLANEOUS

                  6.1 EXPORT  CONTROL.  The parties  acknowledge  that Products,
Licensed Materials and Information (including,  but not limited to, Services and
training)  provided  under this  Agreement  are subject to U.S.  export laws and
regulations,  and any use or transfer of such Products and  Information  must be
authorized  under  those  regulations.   AT&T  agrees  that  it  will  not  use,
distribute,   transfer,   or  transmit  the  Products,   Licensed  Materials  or
Information  (even if  incorporated  into other  products)  in violation of U.S.
export regulations. If requested by Supplier, AT&T shall sign written assurances
and other export-related documents as may be










required for Supplier to comply with U.S. export regulations.  This Section does
not grant AT&T any contractual right to Export Supplier's  Products and Licensed
Materials.  Such  right  shall  only  be  granted  expressly  in  an  applicable
Supplemental Agreement.

                  6.2  PUBLICATION  OF  AGREEMENT.  The parties  shall treat the
provisions  of  this  Agreement  and any  Supplemental  Agreement  or any  Order
submitted  hereunder  as  Information  subject  to the  restrictions  on use and
disclosure  set forth in Section 4.1, USE OF  INFORMATION,  except as reasonably
necessary  for  performance  hereunder  (including   enforcement  of  Supplier's
obligations under the Pricing  Agreement and AT&T's  obligations under Exhibit 1
thereto) and except to the extent  disclosure may be required by applicable laws
or regulations, in which latter case, the party required to make such disclosure
shall promptly  inform the other prior to such  disclosure in sufficient time to
enable  such  other  party  to make  known  any  objections  it may have to such
disclosure.   The  party  required  to  disclose  information   concerning  this
Agreement, a Supplemental Agreement or Order to a third party in accordance with
the previous  sentence  shall take all  reasonable  steps to secure a protective
order or otherwise  assure that the Agreement,  Supplemental  Agreement or Order
will be withheld from the public record.

                  6.3  NOTICES.  All notices  under this  Agreement  shall be in
writing (except where otherwise stated) by confirmed, facsimile, electronic mail
or similar communication, or by certified or registered mail.
Within ten (10)
days  following  the  Effective  Date,  the parties will  exchange the names and
addresses  to whom the notices  should be sent. A notice shall be deemed to have
been given, if by electronic mail,  facsimile or similar  communication,  on the
date it is sent,  and, if by certified  or  registered  mail,  on the date it is
deposited postage prepaid. Communications may be made orally between the parties
when the nature of the  communication  does not require written  notice.  In the
event of a change  of  address,  written  notice of such  change  shall be given
promptly to the other party.

                  6.4 ORDERING  COMPANY'S  RESPONSIBILITY.  (a) Ordering Company
shall, at no charge to Supplier, provide Supplier with notice of site conditions
known to Ordering  Company and such  electrical  and  environmental  conditions,
technical  information,  data, technical support or assistance as may reasonably
be required by Supplier to fulfill its  obligations  under this  Agreement,  any
Supplemental  Agreement  or Order.  If  Ordering  Company  fails to provide  the
required  conditions,   technical  information,  data,  support  or  assistance,
Supplier shall be discharged from its obligations to perform  hereunder for that
Order.  Where  Services are to be  performed  by Supplier in buildings  owned or
controlled  by Ordering  Company,  Ordering  Company  shall be  responsible  for
ensuring  that the  premises  where the work is to be  performed by Supplier are
accessible  to Supplier  and ready and suitable for the Services to be performed
in   accordance   with   Supplier's   reasonable   site-preparation   conditions
communicated in advance to Ordering Company.  Such conditions  include,  but are
not limited to, (a) site readiness and (b) access to adequate  storage space for
tools and other small items  necessary  for the work,  working  space,  personal
facilities,  heat,  light,  ventilation,   telephone,  electrical  current,  and
outlets, all provided within a reasonable distance of the area where the work is
to be performed, if available.









                  (b) Supplier's  representative shall have the right to inspect
the site prior to Service Start Date.  If Ordering  Company or its other vendors
or contractors fail to timely complete site readiness or if the work of Ordering
Company  or  its  other  vendors  or  contractors   interferes  with  Supplier's
performance,  the applicable  Completion  Date shall be extended as necessary to
compensate  for such  delay or  interference  and  additional  charges  shall be
invoiced to recover the additional  expenses incurred by Supplier as a result of
such failure or interference.  Moreover,  should Ordering Company fail to comply
with the reasonable site-preparation conditions after Supplier provides Ordering
Company notice,  Supplier may perform such work or furnish such items and charge
Ordering  Company  for them in  addition  to the  prices  otherwise  charged  by
Supplier for such Services.

                  6.5  SUPPLIER'S  RESPONSIBILITY.  (a)  Supplier  shall  become
acquainted  with  conditions  governing  the  delivery,  receipt  and storage of
materials  at the site of the work so that  Supplier  will  not  interfere  with
Ordering Company's operations.  For items other than those identified in Section
6.4,  ORDERING  COMPANY'S   RESPONSIBILITY,   above,   storage  space  will  not
necessarily be provided  adjacent to the site of the work.  Therefore,  Supplier
shall be expected to select,  uncrate,  remove and transport  materials from the
storage areas provided. Except to the extent that Supplier's property located on
Ordering   Company's  property  is  damaged  or  misappropriated  by  employees,
contractors or  representatives  of Ordering  Company,  Ordering  Company is not
responsible  for the  safekeeping of such  property.  When  Supplier's  property
located  on  Ordering  Company's  property  is  damaged  or  misappropriated  by
employees, contractors, or representatives of Ordering Company, Ordering Company
shall be liable to Supplier for such damage or misappropriation.  Supplier shall
not stop,  delay or interfere with Ordering  Company's work schedule without the
prior  approval  of  Ordering  Company.  Supplier  shall  provide  and  maintain
sufficient covering and take any other precautions necessary to protect Ordering
Company's  stock,  equipment  and other  property  from damage due to Supplier's
performance of the work.

                  (b)  Supplier  recognizes  that  the  continuity  of  Ordering
Company's  telecommunications  services is of paramount  importance  to Ordering
Company,  and Supplier  shall at all times exercise  reasonable  care to prevent
damage to  Company's  plant and shall not use any  equipment  or  methods  which
Ordering  Company  has  informed  Supplier,  either in writing  or through  oral
directives at the work site, might endanger or interfere with its service.

                  6.6 EACH PARTY'S RESPONSIBILITY.  Each party shall be entirely
responsible for all persons that it furnishes working in harmony with all others
when  working  on the other  party's  premises  or those of  Ordering  Company's
customers.   Services  performed  by  either  party  or  its  other  vendors  or
contractors shall not interfere with the other party's performance of services.

                  6.7 ASSURANCE OF SUPPLY. (a) AT&T and Supplier
will jointly
conduct regularly scheduled Life Cycle Management reviews for the
purpose of
sharing information concerning current and future Product and
support
requirements in order to permit both parties to make informed
decisions
concerning such matters. AT&T's priority is to assure the ongoing











growth and service capabilities of the network are satisfied. In order to ensure
the long term  viability  of the  network,  AT&T will have the option to request
sustained manufacturing service for all Products and components that are used in
the network.

                  (b)  Supplier  must  provide  written   notification  to  AT&T
eighteen (18) months in advance of Supplier's intended date of DA of any Product
used in Ordering Company's network,  or to substitute or replace such Product if
Form, Fit or Function is affected. Supplier will provide nine (9) months written
notice with  regard to BCS  Products  not used in Order  Company's  network.  If
Supplier's  vendor  terminates  production  of a Product  and/or  component of a
Product,  Supplier  will use  reasonable  efforts to  provide  the  Products  or
components or secure sources for such Products or components;  provided however,
that  Supplier  reserves  the right to  provide  a  shorter  notice in the event
suppliers  of  a  Product  or  critical  component   terminates   production  or
maintenance  of such items and no other  sources  for such items can be secured.
Within  six  (6)  months  of  notification  of DA,  AT&T  will  provide  written
notification  to Supplier  that it concurs with  Supplier's  decision or that it
intends to negotiate the terms,  conditions and prices under which  availability
shall be  extended,  provided  that  such  Product  and/or  its  components  are
available  to  Supplier.  Unless  otherwise  agreed to, the  framework  for that
agreement  is that  Supplier  will be entitled to recover its costs of providing
continued  availability,  plus a reasonable  profit.  Software DA is governed by
Section 9.20, NOTIFICATION OF DISCONTINUED AVAILABILITY OF SOFTWARE.

                  6.8 PUBLICITY. Each party shall submit to the other a proposed
copy of all advertising  wherein the name,  trademark,  code,  Specification  or
service mark of the other party or its  Affiliates is  mentioned.  Neither party
shall  publish  or use  such  advertising  without  the  other's  prior  written
approval, which consent shall not be unreasonably withheld or delayed.

                  6.9 RIGHT OF  ACCESS/PERMITS  AND APPROVALS.  Each party shall
have the right to enter the premises of the other party during  normal  business
hours with respect to the  performance of this  Agreement,  subject to all plant
rules and regulations,  security  regulations and procedures and U.S. Government
clearance  requirements if applicable.  No charge shall be made for such access.
Reasonable prior notification  shall be given when access is required.  Ordering
Company shall have the responsibility for obtaining all state, local and federal
approvals and permits prior to the  commencement  of the work. Any limitation of
or delay in  providing  timely  access  may  result  in a change  of  Supplier's
schedule for performing  its  obligations  hereunder and  additional  charges to
recover additional expenses incurred by Supplier as a result of such limitations
or delays.

                  6.10 FORCE  MAJEURE.  Neither party shall be held  responsible
for any delay or failure in performance to the extent that such delay or failure
is caused by a Force Majeure; provided, however, that Ordering Company shall not
be  relieved  by reason of such  cause of its  obligation  to make  payments  to
Supplier.  If any Force Majeure condition occurs, the party delayed or unable to
perform shall give prompt  notice to the other party,  stating the nature of the
Force  Majeure  condition  and any action  being taken to avoid or minimize  its
effect.  The  party  affected  by the  other's  delay or  inability  to  perform
(hereinafter the "Affected Party") may elect












to: (a) suspend the applicable  Supplemental Agreement or Order for the duration
of the Force Majeure condition and (i) only to the extent  reasonably  necessary
to maintain the normal  operation of the Affected Party's  business,  buy, sell,
obtain or furnish  elsewhere  the Product,  Licensed  Material or Services to be
bought,  sold, obtained or furnished  thereunder (unless such sale or furnishing
is prohibited  under this  Agreement,  a Supplemental  Agreement or an Order, in
which event an Ordering  Company  experiencing a Force Majeure  condition  shall
bear Supplier's  reasonable costs (including  inventory costs) incurred awaiting
cessation  of the Force  Majeure  condition)  and, at the option of the Affected
Party,  deduct  from any  commitment  the  quantity  bought,  sold,  obtained or
furnished or for which  commitments  have been made  elsewhere and (ii) once the
Force  Majeure  condition  ceases,   resume  performance  under  the  applicable
Supplemental  Agreement or Order with an option in the Affected  Party to extend
the period of such Supplemental  Agreement or Order up to the length of time the
Force  Majeure  condition  endured  and/or (b) when the delay or  nonperformance
continues for a period of at least thirty (30) days, terminate, at no charge and
without any  liability,  the applicable  Supplemental  Agreement or Order or the
part of it relating to Products or Licensed  Material  not already  shipped,  or
Services not already performed. Unless written notice is given within forty-five
(45) days after the Affected  Party is notified of the Force Majeure  condition,
option (a) shall be deemed selected. Nothing contained herein or elsewhere shall
impose any obligation on either party to settle any labor difficulty.

                  6.11 INDEPENDENT  CONTRACTOR.  All work performed by Supplier,
AT&T or an  Ordering  Company  under this  Agreement  shall be  performed  as an
independent  contractor  and  not as an  agent  of  the  other,  and no  persons
furnished by the performing party shall be considered the employees or agents of
the other.  Each party is wholly  responsible for withholding and payment of all
federal,  state,  and local income and other  payroll  taxes with respect to its
employees, including contributions from them as required by law.

                  6.12 RELEASES  VOID.  Neither party shall require  releases or
waivers of any personal rights from representatives or employees of the other in
connection  with  visits to its  premises,  nor shall  such  parties  plead such
releases or waivers in any action or proceeding.

                  6.13 SURVIVAL OF OBLIGATIONS. The rights and

                  6.14 GOVERNMENT  CONTRACT  PROVISIONS.  Ordering Company shall
identify in a request for proposed Supplemental Agreement if a Product, Licensed
Material or Service to be  provided  by  Supplier  is  intended  for use under a
government  contract and if government  contract flowdown provisions shall apply
to such procurement, with identification of such flowdown










provisions.  In such a case,  Supplier  will  advise  AT&T if it will  submit  a
proposal,  bid or accept an Order on such basis and, if so, it will  address its
acceptance or compliance with the flowdown terms and conditions in its proposal,
bid or Supplemental  Agreement.  Orders placed in accordance with such proposal,
bid or  Supplemental  Agreement  will be  subject to the  identified  government
contract provisions as negotiated.  If an Order or Supplemental  Agreement fails
to specify the  inclusion of  government  flowdown  clauses or is issued by AT&T
without the prior  identification of government contract use or flowdown clauses
as provided  above,  Supplier  shall have the right to  terminate  such Order or
Supplemental  Agreement and collect from Ordering  Company  charges for expenses
incurred until the effective date of such termination.

                  6.17   UTILIZATION  OF  MINORITY  AND   WOMEN-OWNED   BUSINESS
ENTERPRISES.  It  is  AT&T's  policy  that  minority  and  women-owned  business
enterprises  ("MWBE's)  as  defined  in  Exhibit  6-1  shall  have  the  maximum
practicable opportunity to participate in the performance of contracts. Supplier
agrees to use its good faith efforts to utilize  MWBE's to carry out this policy
to the fullest extent consistent with the efficient  performance of its business
and this










Agreement.  In addition to these general  conditions for MWBE support,  provided
that Ordering  Company will work with Supplier to seek out MWBE's and works with
Supplier in the  development of  opportunities  for the use of MWBE's,  Supplier
agrees  to (a) work with  Ordering  Company  to  develop  opportunities  for the
utilization  of MWBE's  for  first  tier  procurement  of  Supplier's  Products,
Licensed  Materials  and  Services by Ordering  Company,  (b) use its good faith
efforts to utilize MWBE's in support of this Agreement and strive to achieve the
portion of total expenditures for all Products,  Licensed Materials and Services
purchased  from  Supplier  equal  to 5% of  the  value  of  Ordering  Companies'
purchases of Products,  Licensed  Materials  and Services from Supplier in 1996,
and strive to increase such  percentage  by 10% each of the  following  years of
this Agreement and (c) support Ordering  Companies' state and regional goals for
MWBE  and   service-disabled   veterans   spending  in   California   and  other
states/regions  as may be defined in the  future.  Supplier  agrees to conduct a
program which will enable MWBE's to be considered fairly as  subcontractors  and
suppliers under this Agreement.  Supplier shall submit to AT&T periodic  reports
of work with known  MWBE's in the form of Exhibit 6-1 in such manner and at such
time (not more than  quarterly) as AT&T's  representative  may  prescribe.  Such
periodic  reports shall state  separately for MBE's and WBE's the  subcontracted
work which is  attributable  to Ordering  Companies.  In instances  where direct
correlation  cannot be  determined,  such MWBE  payments may be  established  by
Supplier comparing  Ordering Company's payments to Supplier,  in that period, to
total payments to Supplier from all of its customers,  in that period,  and then
arriving at Ordering Company's  apportionment of such MWBE payments.  Nothing in
this clause shall affect or diminish Supplier's  obligations as set forth in the
assignment and subcontracting provisions.

                  6.18 ASSIGNABILITY. Except as provided in this clause, neither
party shall assign this Agreement or any right or interest under this Agreement,
nor delegate any work or  obligation  to be performed  under this  Agreement (an
"assignment")  without the other party's prior  written  consent.  Any attempted
assignment  in  contravention  of this  clause  shall be void  and  ineffective.
Nothing shall  preclude a party from employing a  subcontractor  in carrying out
its obligations under this Agreement; provided, however, that if Supplier uses a
subcontractor  to perform a material service or obligation under this Agreement,
such use will be  subject  to AT&T's  written  consent.  Supplier's  use of such
subcontractor  shall  not  release  Supplier  from its  obligations  under  this
Agreement.  Notwithstanding  the  foregoing,  Supplier  shall  have the right to
assign this Agreement and to assign its rights under this Agreement, in whole or
in part,  to any present or future  Affiliate or to any entity  which  purchases
from  Supplier  the  operating  asset(s)  utilized  by  Supplier  to fulfill its
obligations  hereunder,  subject to AT&T's written consent,  which consent shall
not be unreasonably withheld; provided, however, that in any such event Supplier
shall not be released from its obligations hereunder and shall indemnify, defend
and hold  harmless each  Ordering  Company for all losses or damages  arising in
connection  therewith,  including  from any  breach  of this  Agreement  by such
assignee.  The notice of  assignment  shall state the  effective  date  thereof.
Following the effective date and to the extent of the assignment, Supplier shall
not be released from obligations.  For purposes of this clause,  the "Agreement"
includes this Agreement,  each Supplemental Agreement,  each Order and any other
subordinate agreement placed under this Agreement.









                  6.19 GOVERNING LAW. Except as set forth in Section 5A.10,  LAW

agrees to indemnify, defend (at the other party's request) and save harmless the
other party, its Affiliates, its and their customers and each of their officers,
directors and employees from and against any losses,  damages,  claims, demands,
suits,   liabilities,   fines,  penalties  and  expenses  (including  reasonable
attorney's  fees) that arise out of or result  from (i) failure to do so or (ii)

to Ordering Company. Supplier shall bear the cost of such auditing.

                  6.22  NON-WAIVERS.  The failure of either party at any time to

to be a waiver  of such  right or remedy  with  respect  to any other  breach or
failure by the other party.

                  6.23 THIRD PARTY  BENEFICIARIES.  Except as otherwise provided

Supplemental  Agreement  shall provide any third person with any remedy,  claim,
liability,  reimbursement,  claim of  action  or other  right in excess of those
existing without reference to this Agreement or any Supplemental Agreement.

                  6.24  SEVERABILITY.  If any provision of this Agreement or any
Supplemental  Agreement or the application thereof to any person or circumstance
is  determined  by a court of  competent  jurisdiction  to be  invalid,  void or
unenforceable, the remaining provisions hereof or thereof, or the application of
such provision to persons or circumstances  or in jurisdiction  other than those
as to which it has been held  invalid  or  unenforceable,  shall  remain in full
force  and  effect  and shall in no way be  affected,  impaired  or  invalidated
thereby, so long as the economic











or legal substance of the transactions  contemplated  hereby or thereby,  as the
case may be, is not  affected  in any manner  adverse  to any  party.  Upon such
determination,  the parties shall  negotiate in good faith in an effort to agree
upon such a suitable and  equitable  provision to effect the original  intent of
the parties.

                       PURPOSE AND ORGANIZATION OF PART II

                  7.1  PURPOSE  AND  SCOPE OF PART II.  Part II
sets  forth  the
specific  additional  terms and  conditions  pursuant  to which
Supplier  shall
provide,  and Ordering Company shall purchase or license,
Supplier's  Products,
Licensed   Materials   and   Services   that   relate   to  the   operation   of
telecommunications network infrastructure.  The terms and conditions of Ordering
Company's  purchase and licensing of Products,  Licensed  Materials and Services
provided by Supplier's Global Business  Communications Systems business unit are
set forth in Part III. A non-exclusive list of the specific  Products,  Licensed
Materials  and  Services  is  set  forth  in  the  Product  Information  Catalog
Extraction  System  ("PRICES")  database.  Supplier may at any time, and without
consent of Ordering  Company,  revise or otherwise amend that database solely to
add to it additional  items offered by Supplier  under Part II.  Supplier  shall
remove items from that database only in accordance  with Section 6.7,  ASSURANCE
OF SUPPLY.  Failure of  Supplier  to list a Product or Service in that  database
shall not preclude Supplier from providing such item pursuant to Part II.

                  7.2 ORGANIZATION OF PART II. Part II is
organized as follows:

                  8.1  GENERAL.  The  provisions  of this  Article  8  shall  be
applicable to the purchase of Products from Supplier.  If Software is also to be

also be applicable.









                  8.2 PRODUCT WARRANTY. (a) Supplier warrants to
Ordering Company only, that:

                           (i) As of the date title  passes,
Supplier will have
         the right to sell,  transfer,  and assign such  Products
and the title
         conveyed by Supplier shall be good and Products shall be
delivered free
         from any security interests or any other liens or
encumbrances ;

                           (ii) Upon  shipment or, if installed by
Supplier upon
         Acceptance,  Supplier's  Manufactured  Products  will be
new (except if
         manufactured  discontinued,  or with Ordering Company's
approval), free
         from defects in material, workmanship, and design (except
to the extent
         (A)  designed,  in whole or in part,  by  Ordering
Company  or persons
         furnished by Ordering Company; or (B) such design defects
are caused by
         the  presence  in   Supplier's   Manufactured   Product
of  substitute
         components  of Ordering  Company's  selection  and not
recommended  by
         Supplier),  and will conform to Supplier's
Specifications or any other
         agreed-upon  Specifications  referenced in the Order for
such Products;
         and

                           (iii) With respect to Vendor Items,
Supplier, to the
         extent permitted, does hereby assign to Ordering Company
the warranties
         given to Supplier by its vendor of such Vendor Items.
Such  assignment
         will be  effective on the date of shipment of such
Vendor  Items.  With
         respect to Vendor Items  recommended by Supplier in its
Specifications
         for which the Vendor's warranty cannot be assigned to
Ordering Company,
         or if  assigned,  less  than  sixty  (60) days  remain of
the  Vendor's
         warranty at the time of  assignment,  Supplier  warrants
for sixty (60)
         days from date of shipment or if installed by Supplier
from  Acceptance
         that such  Vendor's  Items will be free from  defects in
material  and
         workmanship and will conform to Supplier's
Specifications or any other
         agreed-upon Specification referenced in the Order for
such Products.

                           (iv)  Neither  inspection,
Acceptance,  nor  payment
         shall affect or reduce the term of any warranty.

                  (b) The Warranty  Period for a Product is set forth in Exhibit
8-1.  The  Warranty  Period for a Product or part  thereof  repaired  under this
Warranty is the period indicated in Exhibit 8-1.

                  (c) If,  under  normal and  proper  use during the  applicable
Warranty Period, a defect or nonconformity is identified in a Product  furnished
by Supplier, Ordering Company shall notify Supplier in writing of such defect or
nonconformity   promptly  after  Ordering  Company   discovers  such  defect  or
nonconformity  and  follow  Supplier's  instructions  regarding  the  return  of
defective or nonconforming Product. With respect to a defect or nonconformity of
Products to  Supplier's  Specifications  or any other agreed upon  Specification
referenced  in the Order for such  Products,  Supplier  shall take the following
action promptly:










                           (i)  Within  the first  sixty  (60)
days  after  (aa)
         installation  completion  of a Product,  if Supplier has
installed the
         Product or (ab) delivery, if Supplier is not installing
the Product, if
         Ordering  Company  notifies  Supplier of a defect or
nonconformity  of
         Products  to the  Specifications,  that does not  appear
to be  curable
         through repair or replacement within a reasonable time
period, Ordering
         Company will be entitled,  at its option,  to a refund of
the Product's
         purchase price and  installation  charges and the
associated  Licensed
         Materials charges.  Should Ordering Company seek such a
refund, it will
         provide  Supplier such  cooperation as necessary to
enable  Supplier to
         remove the Product from Ordering Company's premises,  if
necessary.  In
         the event of such refund,  Ordering  Company may also
return for credit
         any other  Products  intended for use with the
defective  Product that
         cannot be applied to another  use by  Ordering  Company
and may cancel,
         without liability for cancellation charges, any pending
Orders for such
         Product.

                           (ii)  After  sixty  (60) days from
(aa)  installation
         completion of a Product,  if Supplier has installed the
Product or (ab)
         delivery,  if Supplier is not installing the Product,
with respect to a
         defect or  nonconformity  of  Products  to  Supplier's
Specifications,
         Supplier shall take the following action promptly:

                                    (A) Supplier, at its option,
shall attempt
         first to repair or  replace  such  Product  without
charge  or, if not
         feasible,  provide a refund or credit  based on the
original  purchase
         price,  installation  charges paid by Ordering  Company
if installed by
         Supplier,  and the  associated  Licensed  Materials
charges.  Ordering
         Company  must return  Product to Supplier  for repair
and  replacement,
         except as noted in  Sections  8.2 (c) (ii) (B) and (C).
In the event of
         such  refund,  Ordering  Company  may also  return for
credit any other
         Products  intended  for use with the  defective  Product
that cannot be
         applied to another  use by Ordering  Company  and may
cancel,  without
         liability  for  cancellation  charges,  any  pending
Orders  for  such
         Product.

                                    (B) Supplier, in the case of
any service
         affecting  defect,  shall  either (1) repair  such
defect in the field
         using best reasonable efforts to avoid any service
interruption; or (2)
         immediately  replace  the  defective  Product,  Licensed
Material,  or
         Service with a working replacement, at Supplier's
expense, for the time
         that it takes the original Product, Licensed Material, or
Service to be
         repaired.  At Ordering Company's option,  Ordering
Company may elect to
         retain  the  replacement  Product,  Licensed  Material,
or  Service if
         substitution of the original after repair could cause a
further service
         interruption. Where Supplier has elected to repair or
replace a Product
         (other than Cable and Wire  Products)  which has not
been  installed by
         Supplier  and  Supplier  ascertains  that the  Product
is not  readily
         returnable  by Ordering  Company,  Supplier  will repair
or replace the
         Product at Ordering  Company's  site.  For the purposes
of Sections 8.2
         (c) (ii) (B) and (C) and Section 8.2 (d), Cable and Wire
Products shall
         mean  fiber  optics  and  associated  products  and
copper  cable  and
         associated  products,  including,  but not limited to,
interbay cable,
         closures, arrays, and mounts.









                                    (C) With respect to Cable and
Wire Products
         which Supplier has ascertained  are not readily
returnable for repair,
         whether or not installed by Supplier,  Supplier may elect
to repair the
         Cable and Wire Products at Ordering Company's site.

                  (d) If  Supplier  has elected to repair or replace a defective
Product,  Ordering  Company is  responsible  for removing and  reinstalling  the
Product and, in addition,  for on-site  repair or  replacement of cable and wire
products,  Ordering  Company  must make the  Product  accessible  for  repair or
replacement, and is responsible to restore the site.

                  (e)  Products  returned  for  repair  or  replacement  will be
accepted by Supplier only in accordance with its instructions and procedures for
such returns. The transportation  expense associated with returning such Product
to Supplier shall be borne by Ordering  Company.  Supplier shall pay the cost of
transportation   of  the  repaired  or  replacing  Product  to  the  destination
designated by Ordering  Company.  The same Product or part shall not be returned
by Supplier to Ordering Company with the notation no-trouble-found (NTF) on more
than two (2)  occasions.  On the third  occasion that a Product or part has been
classified by Supplier as NTF, the Product or part shall be returned to Supplier
and shall become Supplier's property. Supplier shall ship a new, refurbished, or
reconditioned  replacement to Ordering  Company for the returned Product or part
at no charge for that  Product  under  warranty.  For out of  warranty  Product,
Supplier shall ship a new, refurbished, or reconditioned replacement to Ordering
Company for the returned Product or part at Supplier's  current negotiated price
for the production equipment element/component.

                  (f) The defective or nonconforming Products or parts which are
replaced  shall  become  Supplier's  property.  Supplier  may  use  either  new,
remanufactured,  reconditioned, refurbished, or functionally equivalent Products
or parts in the  furnishing  of repairs or  replacements  under this  Agreement.
Unless otherwise agreed or unless unavailable, Supplier shall use new components
in the repair of Products.

                  (g) If a Product for which warranty  Service is claimed is not
defective or is in conformance,  Ordering  Company shall pay Supplier's costs of
handling, inspecting, testing, and transporting, and, if applicable,  reasonable
traveling and related expenses as referenced in Section 3.1 (g), PRICES.

                  (h)  Supplier  makes no  warranty  with  respect to  defective
conditions or  nonconformities  resulting from the following:  Ordering  Company
modifications,  misuse, neglect,  accident or abuse, improper wiring, repairing,
splicing,  alteration,  installation,  storage  or  maintenance  other  than  by
Supplier,  use in a  manner  not  in  accordance  with  Supplier's  or  vendor's
Specifications or operating instructions or failure of Ordering Company to apply
previously   applicable  Supplier   modifications  and  corrections  which  were
available  without extra charges and which  Ordering  Company had had reasonable
opportunity  to apply.  In addition,  Supplier makes no warranty with respect to
Products  which have had their serial  numbers or month and year of  manufacture
removed or altered and with  respect to  expendable  items,  including,  without
limitation, fuses, light bulbs, motor brushes, and the like.










                  (i) THE FOREGOING PRODUCT  WARRANTIES ARE
EXCLUSIVE AND ARE IN
LIEU OF ALL OTHER EXPRESS AND IMPLIED  WARRANTIES,  INCLUDING BUT
NOT LIMITED TO
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE,  EXCEPT FOR
(a)  TANGIBLE  PROPERTY  DAMAGE AND PERSONAL  INJURY FOR WHICH
SUPPLIER IS HELD
LIABLE  AND (b) THE  REMEDY  PROVIDED  IN SECTION  5.1(e),
ORDERING  COMPANIES'
REMEDIES,  ORDERING  COMPANY'S  SOLE AND  EXCLUSIVE  REMEDY SHALL
BE  SUPPLIER'S
OBLIGATION  TO REPAIR,  REPLACE,  CREDIT,  OR REFUND AS SET FORTH
ABOVE IN THIS
WARRANTY.

                  8.3 CONTINUING PRODUCT SUPPORT - PARTS AND
SERVICES.

                  (a)  In  addition  to  repairs   provided  for  under  Product
Warranty,  Supplier  offers repair  services and repair parts in accordance with
Supplier's  repair and repair parts practices and mutually agreed upon terms and
conditions  then  in  effect  for  Supplier's  Manufactured  Products  furnished
pursuant to this  Agreement.  Such  repair  Services  and repair  parts shall be
available  while Supplier is  manufacturing  or stocking such Products or repair
parts,  and in any event for ten (10) years from  Supplier's  last shipment of a
host system to Ordering Company for Supplier's 5ESS Switch System,  and five (5)
years or the duration of the period of the host system, whichever is longer, for
other  5ESS  Switch  Products  sold to  Ordering  Company as an  addition  to an
existing 5ESS Switch System.  The period for all other  Supplier's  Manufactured
Products  is five (5)  years  after  such  Product's  discontinued  availability
effective  date unless  modified by  Supplemental  Agreements.  Supplier may use
either  new,  remanufactured,   reconditioned,   refurbished,   or  functionally
equivalent  Products or parts in the furnishing of repairs or replacements under
this Agreement.

                  (b) If after the agreed to support  period  Supplier is unable
to  provide  repair  part(s)  and/or  repair  service  (s)  and  a  functionally
equivalent  replacement has not been designated,  Supplier shall advise Ordering
Company,  by  written  notice  prior to such  discontinuance  to allow  Ordering
Company to plan  appropriately,  and if Supplier  is unable to identify  another
source of supply for such repair  part(s)  and/or  repair  service(s),  Supplier
shall provide Ordering Company,  upon request,  with  nonexclusive  licenses for
manufacturing drawings and Specifications of raw materials and components to the
extent  Supplier can grant such  licenses,  so that  Ordering  Company will have
sufficient  information  to have  manufactured,  or obtain such Service or parts
from other  sources.  License  terms for the foregoing  manufacturing  drawings,
Specifications,   and  related   documentation,   such  as  manufacturing   shop
instructions,  test programs and test  instructions,  including charges mutually
agreed to, will be in accordance  with Supplier's  licensing  procedures then in

manufacturing  (i.e. any custom or legacy products  requiring unique procedures,
such as NGLN, DDM1000,  FT-Series G and projects such as Customer Connectivity).
Special Product or unique arrangements will require a Supplemental  Agreement to
document the agreements made specifically for that Product or project only.

                  (b) Supplier and Ordering  Company shall identify  Products or
technologies that will require special arrangements and for which Supplemental
Agreements must be negotiated.

                  (c)  Ordering  Company  will  provide to Supplier on a monthly
basis via the Customer Demand Planning (CDP)  mechanized  system,  a forecast of
Product  requirements  consisting  of  funded,  unfunded,  and a  projection  of
unforecasted  demand.  This  forecast is  considered  unconstrained  and will be
provided for a rolling  twelve (12) months as well as an aggregate  forecast for
the subsequent year. It will represent forecasted demand by fiscal month.

                  (d)  A  current   listing  of  Products   that  are  presently
forecasted by Network Services Division/Inventory  Management ("NSD/IM") will be
mutually  agreed upon and updated  periodically  as the scope of the forecasting

encompass all of the network Product requirements for Ordering Companies.









                  (e) Orders will be placed within Supplier's  planning interval
documented in Exhibit 2-1, Planning Intervals,  to the extent possible, and will
constitute  a  commitment  to buy.  Ordering  Company  will  compare the monthly
forecast with the  semi-annual  planning  forecast  being  provided in April and
September,  and  will  reconcile  the two  accordingly.  In the  future,  if the
frequency of these forecasts changes, a similar reconciliation will be performed
on all Product  elements that are provided in the planning  forecasts.  Ordering
Company  and  Supplier  will  review  Ordering  Company's  forecasting  accuracy
quarterly with the goal of obtaining 80% forecasting accuracy.  Ordering Company
will work with Supplier to provide Product level requirements on a monthly basis
especially  for those  forecasts  within the six (6) month window as part of the
rolling forecast.

that is specific to Ordering  Company's needs,  such  modification to the system
shall be made at a cost mutually  agreed upon by Ordering  Company and Supplier.
Supplier  shall  provide  Ordering  Company  with  CDP  system  support  via the
1-800-CDP-8845 Hotline at no cost to Ordering Company.

                  (g) METRICS.  Ordering  Company and Supplier  agree to monitor
forecast accuracy on a monthly basis.  Forecast accuracy  measurements  shall be
based  upon a two month  lead time for each  forecasted  item.  CDP shall be the
vehicle  for  gathering  data on forecast  accuracy  and  shipping  performance.
Ordering Company will monitor its forecasts and seek to achieve  improvements in
accuracy as described in Exhibit 8-3.  Supplier will monitor and seek to achieve
improvements on performance to customer  requested  completion date (CRCD),  and
performance to published order  intervals.  This is an informal process and does
not imply  penalty for  non-performance.  The 1996 metric goals are set forth in
Exhibit  8-3.  Joint  goals  and  metrics  for  future  years  will be  mutually
negotiated for continuous improvement.

                  (h)  FORECASTING  PROCESS   MONITORING.
Forecasting  Process
Performance  Goals  will be  monitored  on an  ongoing  basis  by the  Inventory

Unless  otherwise  agreed  by  the  parties,  Ordering  Company  shall  have  an
Acceptance Test Period of thirty (30) consecutive  calendar days to conduct this
test. The Software shall be deemed accepted by Ordering  Company unless Ordering
Company notifies  Supplier in writing to the contrary within the Acceptance Test
Period  described  above.  If the Software fails the Acceptance  Test during the
Acceptance  Test Period,  Supplier shall use its  reasonable  efforts to correct
each error to minimize the Acceptance  delay,  and the Acceptance  Date shall be
extended on a day-to-day  basis until the  Software,  as modified,  is accepted.
Acceptance of a particular  release of Software in the ITN or in the First Field
Application  shall  constitute  Acceptance  of all copies of such Software to be
provided Ordering Company, regardless of when each such copy of such Software is
installed on its Designated Processor.

                  (b) If  Ordering  Company  elects in the Order not to  perform

                  (c) For an Acceptance  Test  conducted by Ordering  Company on
newly  licensed  Software,  Supplier  will,  at Ordering  Company's  request and
without charge,  provide a reasonable level of technical  assistance to Ordering
Company when difficulties are encountered by Ordering Company.

                  (d) In the event that  Software has not passed the  Acceptance
Test  within six (6) months  after the  Delivery  Date,  at  Ordering  Company's
option, (i) Ordering Company shall return all copies of the Software to Supplier
and Supplier shall reimburse Ordering Company for any fees (e.g.,  license, R&D,
etc.)  paid for such  Software  or (ii) if  mutually  agreed to by the  parties,
Ordering Company may retain the Software at an equitable  adjustment in the fees
as may be agreed to by the parties,  in which case the Software  shall be deemed
accepted.

Ordering
Company all of the following:

                           (i)  The  Software  will  be  free
from  significant
         errors,   will   conform  to  and  perform  in
accordance   with  the
         Specifications.  The media  containing  the Software
will be free from
         defects in material and  workmanship.  The Software  will

                           (iii)  There  are  no  copy
protection  or  similar
         mechanisms within the Software which will, either now or
in the future,
         interfere with the rights granted to Ordering Company.

                           (iv)  Supplier has the right to grant
the licenses as
         granted  herein,  and has not  done  anything  to

         damage,  destroy,  or  alter  any data or  other
information  accessed
         through or  processed  by the  Software in any manner.
Supplier  shall
         immediately  advise  Ordering  Company,  in  writing,
upon  reasonable
         suspicion or actual knowledge that the Software  provided
may result in
         the harm described above.

                  (b) All warranties shall survive inspection,

Warranty Period  specified in Exhibit 8-1 Software proves to have a defect which
materially   affects  its   performance   in  accordance   with  the  applicable
Specifications  and Ordering Company notifies Supplier in writing of such defect
promptly after  Ordering  Company  discovers such defect and follows  Supplier's
instructions,  if any, regarding return of defective  Software,  Supplier shall,
attempt first to either correct or replace such Software  without charge,  or if
correction or replacement  is not feasible,  provide a refund or credit based on
the original  license fee. In addition,  should a defect in Software  prevent in
whole or in part the use of any Product(s) that cannot be applied to another use
by Ordering  Company,  Ordering  Company may, at its election,  also return such
Product(s) for a full refund.

                  (d) Software  returned for correction or  replacement  will be
accepted by Supplier only in accordance with its instructions and procedures for
such returns. The transportation expense associated with returning such Software
to Supplier shall be borne by Ordering Company.  Supplier shall pay the costs of
transportation  of the  corrected  or  replacing  Software  to  the  destination
designated by Ordering Company.

                  (e) If Software for which  warranty  Service is claimed is not
defective or  nonconforming,  Ordering  Company  shall pay  Supplier's  costs of
handling,  inspecting,  testing, and transporting and, if applicable,  traveling
and related expenses.

                  (f) Supplier makes no warranty with respect to
defective
conditions or nonconformities resulting from the following:
modifications,
misuse, neglect, or accident; events outside Supplier's control;
installation,
use of Software or Software maintenance in a









manner not in accordance with Supplier's Specifications, operating instructions,
or license-to-use; or failure of Ordering Company to apply previously applicable
Supplier modifications and corrections.  In addition, Supplier makes no warranty
with  respect  to  defects  related  to  Ordering  Company's  data base  errors.
Moreover,  no warranty is made that  Software  will run  uninterrupted  or error
free.     

                  (g) If any  Software  is lost or damaged  during the  Warranty
Period or such other time as  Supplier  maintains  the  Software  as a generally
available product offering, while in the possession of
Ordering  Company,
Supplier  will  promptly  replace  the  Software at the  established  charge for
providing the associated media unless such is provided by Ordering Company.

                  (h) If an Order  specifies that Ordering  Company's use of the
Software  is  limited  to a  designated  site  or a  Designated  Processor,  the
provisions of this clause shall apply. If Ordering Company performs installation
and elects to perform  applicable tests for any Software,  the warranty for such
Software shall commence on the Delivery Date. If Supplier performs  installation
of any Software, the Warranty for such Software shall commence upon installation
completion.

                  (i) If Software is purchased with a license for multiple sites
(e.g.,  unlimited  replication rights, or limited multiple  replication rights),
the  warranty for such  Software  shall  commence  upon  Acceptance  by Ordering
Company in the ITN or in the First Field Application, as appropriate.

                  (j) Supplier  warrants that  installation  of any new Software
will not shorten or lessen the warranty of existing Software.

         economies.  To  the  extent  feasible,  Ordering
Company  will  permit
         Supplier's  personnel  to use luncheon  facilities  in
the building and
         will  license  Supplier  to use  administrative  space

In addition,  for 4ESS switch and 5ESS switch,  the Switching  Software  Support
Plan  (SSP),  defines  how the  level of  support  changes  with  time  upon the
introduction  of new base  releases.  Exhibit 10-2 further  explains the support
service that will be offered during each of the life cycle phases.

                  10.10  ELIGIBILITY FOR MAINTENANCE  SERVICE.  (a) Products and
Software  furnished  and  installed by Supplier  are  eligible  for  Maintenance
Service without initial  evaluation by Supplier  provided the Service  commences
not  later  than the end of the  Warranty  Period.  Unless  otherwise  agreed by
Supplier in writing,  Maintenance  Service for Software  shall only be available
for the generic that is current at the time that such Service is ordered and the
immediately  preceding generic,  as well as a generic where the term of warranty
is still in effect.

                  (b) In all other  situations,  the Products and Software shall
not be eligible for Maintenance Service until Supplier,  at its option, has made
an initial  evaluation to determine  whether  modifications are required to make
the Product or Software eligible. If, in Supplier's judgment,  modifications are
required for this  purpose,  Supplier will provide a written  estimate  based on
standard rates to Ordering Company for making such modifications.  Upon Ordering
Company's written Acceptance, Ordering Company will be billed at Supplier's then
standard  rate  for such  evaluation  and any such  modifications  furnished  by
Supplier.  Software will not be eligible for Maintenance Service unless Supplier
determines  that the Software is in good working  order in  accordance  with its
Specifications and can be maintained in such condition.

                  10.11 ORDERS FOR MAINTENANCE SERVICES. Ordering
Company shall
place Orders for Maintenance Services, indicating the Level of
Service to be
provided for each Product upon commencement of the Order. The
Level of Service
chosen shall remain in effect without



change for the contract period covered by the Order.  All
installations of each
Product  and each  release  of  Software  must be  served  at the
same  Level of
Service.

                  10.12 PRICES.  Sixty (60) days prior to the  expiration of any
fixed-term Service Order, Supplier will, at Ordering Company's request, submit a
price for the renewal of the Service. Charges for time-and-material  Maintenance
Service shall be determined at Supplier's  applicable time and material rates in
effect at the time an Order for such  Service is  accepted  and will be based on
the total  work-hours  (which  includes  travel  time)  expended on the job, and
actual travel expense. Such charges shall be based on a minimum number of hours.

                  10.13 PERIODS OF MAINTENANCE SERVICE.
Maintenance Service will
be provided in accordance with the Level of Service specified in
an Order.

                  10.14 MAINTENANCE SERVICE EXCLUSIONS. (a) Unless

                                    (A) Database Problems - If the
condition is
         mutually  determined  to be the result of  corruption  of
the  Software
         Product data base, and such  corruption is not the direct
result of the
         Product,  the condition  will be referred back to
Ordering  Company for
         resolution.  At Ordering Company's  request,  and at
Supplier's option,
         Supplier  may  prepare a proposal  for  billable
corrective  action to
         correct  Ordering  Company's data base.  However,  if
corruption is the
         result of, or caused by another of  Supplier's  Products
or  Services,
         Supplier shall initiate Problem  Management  regardless
of whether such
         Software Product is covered under an Order.


                                    (B) Hardware/Firmware Problems
- - When a
         condition  has been  isolated to a problem in hardware or
Firmware  not
         covered under this  Agreement,  the condition  will be
referred back to
         Ordering Company for disposition under whatever
arrangements  Ordering
         Company may have for such hardware or Firmware.

                                    (C) Other/Interfacing Problems
- - If the
         condition is determined mutually to be caused by systems
other than the
         Products covered under the existing Order,  including,
but not limited
         to,  systems which  interface  with the Product,  the
condition will be
         referred to Ordering  Company for  corrective  action
unless such other
         system has been  furnished by Supplier,  in which case,
Supplier shall
         initiate Problem  Management.  However,  if a defect is
identified with
         Software  or  Products  covered  by the Order  which is
documented  or
         advertised to interface or work with other systems,
hardware,  Products
         or Software,  Supplier shall conduct restoral and
correction procedures
         as required for a defect and not as Problem Resolution
Management.

                                    (D) Additional Services -
Additional
         services,  including  but not  limited to custom

will be given to
         Ordering  Company as part of the defect  correction  or
Product  Update
         procedure.  Within two (2) years,  a permanent fix will
be published in
         the following release of the related documentation.

                  (c)  NOTIFICATION  OF CORRECTIONS - Supplier  agrees to notify
Ordering  Company of the availability of a resolution or work-around to a defect
reported by Ordering Company.








                  (d) ORDERING  COMPANY  CORRECTIVE  MAINTENANCE  RESPONSIBILITY
Ordering  Company  agrees to install the  corrections or  replacements  provided
under this  Agreement  within a reasonable  period of time.  Ordering  Company's
failure to install emergency fixes, work-arounds, patches or releases will cause
the  Software  Product to be  considered  non-standard  until all such fixes are
installed,  unless Ordering Company has previously notified Supplier of problems
with such emergency fixes, work- arounds, patches or releases.



                  10.18  MAINTENANCE  SERVICES  WARRANTY.  Supplier  warrants to
Ordering Company that  Maintenance  Services will be performed in a professional
manner and in accordance with Supplier's  specifications  or those referenced in
an Order and with accepted practices in the community in which such Services are
performed,  using  material  free from  defects  except  where such  material is
provided by Ordering  Company.  If the Services prove to be not so performed and
if Ordering  Company notifies  Supplier,  within the period of time equal to the
repaired  Product  warranty period (Exhibit 8-1), of the Product being repaired,
or six (6) months,  whichever is less,  commencing  on the date of Acceptance of
the Service,  as  identified in writing by Supplier,  Supplier,  at it's option,
either will correct the defect or  nonconforming  Service for which  Supplier is
responsible or render a full or prorated  refund or credit based on the original
charge for the Services.  After the corrective  action,  Ordering  Company shall
have the right to Acceptance of the corrective work done.


                            D. MISCELLANEOUS SERVICES

                  10.19  TRAINING.  If requested by Ordering  Company,  Supplier

Company;  or, (b) license Ordering Company to reproduce  Supplier's  copyrighted
training modules or manuals, covering those areas of interest outlined in (a) of
this  clause,  sufficient  in detail and format,  to allow  Ordering  Company to
develop and conduct its own training program.

                  10.20  INSTALLATION/CUTOVER  ASSISTANCE. In the event Supplier
is not installing the material,  and if requested by Ordering Company,  Supplier
agrees to make available at the  installation  site, at a negotiated  price plus

the requirements of all permits, licenses and approvals and shall, at all times,
keep a copy of the permits, licenses and approvals at the Site.

                  (d) If Sunday,  holiday,  or night Work is specifically called
for  as  a  permit  requirement,  Supplier  shall  provide  adequate  personnel,
equipment, and supervision for the proper performance and control of the Work in
accordance with such requirement.  For such Work,  Supplier shall be entitled to
extra payment, unless such Work was specifically  contemplated in the applicable
Work Order and included in the Price.

                  (e)  Where  Work  is to be  performed  on  railroad  property,
Supplier shall cooperate with the railroad  personnel in performance of the Work
and shall satisfy railroad requirements.






                  (f) Supplier shall be responsible for all
security affecting
the performance of its Work.

                  11.3 ORDERING COMPANY  FURNISHED  MATERIALS.  (a) All material

completion of the Work, excluding waste.

                  (b)  Supplier  shall  replace all Ordering
Company  furnished
materials  which  are  lost  or  damaged  while  in  the  custody
of  Supplier.
Replacement  materials shall be of a type and quality substantially equal to the

to prevent delay of the Work.

                  (c)  Supplier  shall  rehandle and reload,  if  required,  all
Ordering Company  furnished  materials and equipment which have been rejected by
Supplier.

                  (d)  Ordering  Company  shall  reimburse  Supplier for all its
material shipping and handling expenses associated with:

                 (i) The return and/or replacement of defective

                           (ii) The return of excess  materials
resulting  from
         the  termination  of an  Order  or a  decrease  in  the
quantities  of
         materials  required  to  complete a Work Order for
reasons  other than
         breach of contract or material non-performance by
Supplier.

                           (iii) The return of  materials
provided  by Ordering
         Company  in  excess  of  those  requested  by  Supplier
in the Bill of
         Materials.

                  (e) Unless  expressly  stated to the contrary,  the Price does
not  include  costs for any  Ordering  Company  furnished  material  nor does it
include any Supplier charges for re-engineering,  reinstallation,  modification,
or repair Services to Ordering Company furnished material.  New or used material
(if any)  furnished  by  Ordering  Company  shall be in such  condition  that it
requires no repair and no adjustment or test effort in excess of that normal for
new  material.  Ordering  Company  assumes  all  responsibility  for the  proper
functioning of such material under normal conditions of use and/or when properly
installed.  Ordering  Company shall also provide the necessary  information  for
Supplier to properly install such material.

                  11.4 ORDERING COMPANY OBLIGATIONS.  (a) On or before the start

- -  Except  as
         otherwise   provided   in   Section   11.18,
ARCHAEOLOGICAL   SITES;
         ENVIRONMENTAL  PROTECTION,  Ordering  Company  shall
provide,  or,  at
         Ordering  Company's option,  shall authorize  Supplier to
provide,  any
         consultants for special considerations,  including, but
not limited to,
         biologists to evaluate  endangered species impacts or
archaeologists to
         evaluate historically sensitive sites and qualified
experts to evaluate
         environmentally  hazardous  conditions.  In  the  event
that  Supplier
         provides such  consultants,  Ordering Company shall
reimburse  Supplier
         for such consultant costs on a Lump Sum Price basis; and

                           (ii) EASEMENTS,  PERMITS,  AND RIGHTS
OF WAY - Unless
         otherwise  required by applicable  ordinances,  codes or
statutes,  any
         necessary highway permits,  construction permits,

for by  Ordering
         Company and Ordering  Company shall file, or have filed,
the necessary
         papers (collectively, the "Ordering Company Permits").
Ordering Company
         Permits  and  corresponding  permit  applications,  if
necessary,  are
         included in the Agreement Documents.  If a permit is
unavailable at the
         time of issue of the Agreement  Documents,  the permit
application only
         will appear.  Permits  which are not  available at the
time of issue of
         the Agreement Documents will be provided to Supplier
prior to the Start
         Date  specified  in each Work  Order.  When  permits  not
listed in the
         Agreement  Documents are obtained by Ordering  Company,
a copy will be
         provided to Supplier.

                           (iii) Railroad flagmen and/or
inspectors  required to
         be on the Site as a condition of an easement  permit or

         cost to Supplier.

                  11.5 WORK ORDERS;  CHANGES.  (a) Ordering Company shall submit
Work Orders to Supplier  utilizing  Ordering Company's form. Each Work Order and
Field  Order shall  contain or refer to a document  containing  the  information
necessary for Supplier to fulfill the Work Order, including, but not limited to,
the information  called for by Section 2.1,  ORDERS,  above, a reference to this
Agreement,  Special Conditions,  a Start Date,  Completion Date and a Completion
Schedule.  If such work items have been mutually agreed upon in a writing signed
by the parties  (e.g.,  a  Supplemental  Agreement or a  previously  issued Work
Order),  then Supplier  shall proceed to fulfill the Work Order (i.e.,  the Work
Order shall  function as a notice by  Ordering  Company for  Supplier to proceed
with the Work). If such items have not been agreed upon, Supplier may reject the
Work Order or propose  changes to the Work  Order.  If the parties are unable to
agree, the Work Order shall be deemed abandoned.






                  (b) Each Work  Order and Field  Order  shall be subject to the
terms and conditions of this Agreement  which shall control over any conflicting
provisions in such Work Order.

                  (c)  Changes by  Ordering  Company to an  accepted  Work Order
shall be treated as a separate  Work Order  unless the parties  expressly  agree
otherwise.  In  addition,  subject  to  Section  11.18,   ARCHAEOLOGICAL  SITES;
ENVIRONMENTAL  PROTECTION,  Supplier may identify additional changes to the Work
which must be performed due to certain conditions, as set forth in Section 11.8,
LOCAL  CONDITIONS;  DIFFERING SITE CONDITIONS  below. If any such change affects
Supplier's  ability to meet its obligations  under the original Work Order,  any
Price or  Completion  Date quoted by Supplier with respect to such original Work
Order is subject to change.  All such  changes  must be  approved  in writing by
authorized representatives of both parties using Ordering Company's Form.

                  (d) Minor changes may be made by means of a
Field Order.

                  11.6 PLANT PROTECTION; UNDERGROUND FACILITIES.
(a) Supplier
shall adhere to the applicable MOP with respect to Ordering
Company's
underground facilities.

                  (b)  Ordering  Company  has made  minimal  efforts to identify
existing  utilities  by field  surveys and utility  records  research.  Existing
underground and aerial utilities within the construction  limits of the Work are
indicated on the Drawings only to the extent  information  on such utilities has
been made available to, or discovered by, the Engineer in the performance of the
design  work.  Except to the  extent  that the  information  contains a material
misrepresentation  of fact, the Engineer and Ordering Company expressly disclaim
all  responsibility  for  the  accuracy  and  completeness  of  the  information
indicated.  Supplier shall conduct its operations on the basis that  underground
and aerial utilities may exist which are not indicated on the Drawings.

                  (c)   Supplier   shall  be   responsible   for   locating  and
identifying,  except  for  Ordering  Company's  facilities  or  structures,  all
existing  utilities or  structures  within the  construction  limits of Work and
elsewhere where Supplier's  construction operations may subject the utilities or
structures to damage.  This shall be done prior to the  performance of the Work.
All information  relative to the above shall be recorded and  incorporated  into
the records in a manner reasonably acceptable by the Engineer.

                  (d) For Ordering  Company  facilities or structures,  Supplier
shall adhere to the "One Call" procedure, as set forth in the Specifications.

                  11.7 PROTECTION OF PUBLIC AND PUBLIC PROPERTY.
Subject to any
more stringent requirements of Section 11.18, ARCHAEOLOGICAL SITES;
ENVIRONMENTAL PROTECTION, and Section 6.20, COMPLIANCE WITH LAW:

                  (a) Supplier  shall in the  performance  of the Work  exercise
reasonable  measures to minimize  inconvenience  to the public and shall use its
reasonable efforts to preserve and protect






all trees, shrubs, grass, or other vegetation on or adjacent to the right of way
or Site which do not  unreasonably  interfere  with the Work.  Unless  otherwise
required by Ordering Company's  Representative,  Supplier shall restore all such
property  which may be  disturbed  in the  execution  of its Work to its  former
visible condition.

                  (b) In accordance with  Supplier's  standard  procedures,  all
pavement,  surfacing,  driveways,  curbs, walks,  buildings,  utility poles, guy
wires,  fences,  and other  surface  structures  affected  by  Supplier's  Work,
together  with  all  sod and  shrubs  in  yards  and  parking  areas,  shall  be
substantially  restored to their original visible  condition,  whether within or
outside the easement.  Supplier shall be responsible  for (i) making  reasonably
satisfactory  and  acceptable  arrangements  with the owner of, or the agency or
authority having  jurisdiction over, the damaged property  concerning its repair
or (ii) replacement,  or payment of reasonable costs incurred in connection with
such damage caused by Supplier or its Subcontractors.

                  11.8 LOCAL  CONDITIONS;  DIFFERING SITE  CONDITIONS.  (a) Upon
execution of a Work Order,  Supplier admits to being  reasonably  informed as to
the nature and locations of the Work set forth therein; provided,  however, that
in all cases,  except as  otherwise  provided in Section  11.18,  ARCHAEOLOGICAL
SITES;  ENVIRONMENTAL  PROTECTION,  Differing Site Conditions shall be the basis
for a Change  Order  and  additional  compensation  as set  forth  below in this
Section 11.8.

                  (b) Delays,  Additional  Work,  or extra costs may result from
Differing Site Conditions of which neither  Ordering Company nor Supplier should
reasonably  have had knowledge at the time of the effective  date of the earlier
of the  Supplemental  Agreement,  the Work Order and the Change  Order.  In such
case:

                           (i) Supplier  shall,  promptly  and
before  Differing
         Site Conditions are disturbed,  notify the Engineer in
writing by means
         of the Ordering Company Change Order Form of such
conditions;

                           (ii)  After  receiving  notice  from
Supplier,   the
         Engineer shall promptly investigate the Differing Site
Conditions, and,
         if in his reasonable  judgment,  such  conditions
exist,  the Ordering
         Company  Representative  shall  by  means  of a  Change
Order  make an
         equitable  adjustment  to the Price  and the  Completion
Schedule,  as
         agreed by Supplier; and

                           (iii)  No  claim  of   Supplier   for
an   equitable
         adjustment because of Differing Site Conditions shall be
allowed unless
         written notice has been given as required.

                  11.9 OUTSIDE PLANT SERVICES SCHEDULING. Prior to
the
pre-construction meeting, Supplier shall submit a detailed Outside
Plant
Services Scheduling schedule as set forth in the Specifications.
The Engineer,
Supplier and Ordering Company Representative shall hold






weekly  status  meetings  at mutually  agreed upon times and
places.  Additional
coordination between the parties will be held on an as needed
basis as set forth
in the Specifications.

                  11.10  INSPECTION AND CORRECTION OF DEFECTS;  ACCEPTANCE.  (a)
Ordering Company's  Representative  shall have free access to the Work performed
and  materials  furnished by Supplier  under this  Agreement  for the purpose of
inspection thereof. Prior to the commencement of the Warranty Period (as defined
in Section  11.12,  WARRANTY,  below),  Supplier  shall upon  receipt of written
request from Ordering  Company's  Representative,  furnish  sufficient labor and
facilities  at  Supplier's  expense,  to make  an  inspection  of  Work  already
completed by uncovering and exposing the Work for inspection.

                  (b) If the  inspection  discloses  that  the  Work  reasonably
conforms to the applicable  Specifications in all material respects, the cost to
Supplier  of (i)  uncovering  and  exposing  the Work,  and (ii)  examining  and
restoring  of the Work shall be  considered a Change Order and shall be paid for
by Ordering  Company.  In addition,  if  completion of the Work has been delayed
thereby, Supplier shall be granted a suitable extension of time and/or delay and
disruption  compensation,   as  mutually  determined  by  Ordering  Company  and
Supplier.

                  (c) If the inspection discloses that the Work does not conform
to the applicable  Specifications in all material  respects,  Supplier shall not
have a basis for a Change Order and shall correct the Work at
its own expense.
The  Completion  Date shall not be extended  because of any delay caused by such
non-conforming Work.

                  (d) If  Ordering  Company  notifies  Supplier  of a defect  or
non-conformance  during the progress of the Work or prior to Final Acceptance or
Beneficial  Occupancy,  Supplier will schedule the repair or replacement of such
Work within two (2) work days after receipt of written notice.

                  (e)  Supplier  may  submit  to  Ordering  Company  a notice of
completion,  placing  Ordering  Company on notice that the Work is complete  and
ready for inspection. Ordering Company shall inspect the Work promptly and in no
event later than seven (7) business  days after  receipt of such notice.  In the
event that  Ordering  Company does not inspect the Work within such time period,
Final  Acceptance shall be deemed to have occurred with respect to such Work. If
the inspection  results in a Punch List,  Final  Acceptance shall occur when the
Punch List is complete to Ordering  Company's  reasonable  satisfaction.  Again,
Supplier may submit a notice of completion regarding the Punch List and the same
procedure set forth above shall apply (i.e.,  Ordering Company shall inspect the
Work no later than seven (7)  business  days  after  receipt of such  notice and
Final  Acceptance  shall be deemed if Ordering  Company fails to inspect  within
that time).

                  11.11 SUPERVISION; CONTROL OF WORK. (a) Supplier
shall keep on
the Work site a competent Superintendent and any necessary
assistants and all of
them shall be reasonably satisfactory to Ordering Company's
Representative.






                  (b) Supplier  shall have full control and  direction  (i) over
the mode and manner of doing the Work, subject to Sections 6.20, COMPLIANCE WITH
LAWS, and 11.18,  ARCHAEOLOGICAL SITES;  ENVIRONMENTAL PROTECTION,  and MOPS and
(ii) of its personnel employed on or about the Work.

                  11.12 WARRANTY.

                  (a) FOR  PRODUCTS.  The  Warranty for Products
is set forth in
         Section 8.2, WARRANTY; the Warranty Period is set forth
in Exhibit 8-1,
         provided , however,  that the Warranty  Period begins on
the earlier of
         Final Acceptance of a completed Work Order or Beneficial
Occupancy.

                  (b) FOR SERVICES.  The warranty  shall begin on the earlier of
Final  Acceptance of a completed  Work Order or  Beneficial  Occupancy and shall
extend for one (1) year (the "Warranty Period"). Supplier agrees to perform Work
in a professional manner;  using competent and responsible  personnel trained as
required by the most stringent of accepted industry practice, Supplier practice,
Section 6.20  COMPLIANCE WITH LAWS, and Applicable  EH&S  Requirements  (Section
11.18 (c));  and in  accordance  with the  Specifications  or other  agreed upon
specifications  and in accordance  with  accepted  practices in the community in
which the Work is performed  using  material free from defects except where such
material is provided by Ordering  Company.  If Work provided by Supplier  proves
not to have been so  performed,  and if Ordering  Company  notifies  Supplier in
writing to that effect within the Warranty  Period,  then Supplier shall, at its
option, correct any defects or render a full pro-rated refund or credit based on
the original charges for the Work.

                  (c) If the refund or option is not  chosen and if,  during the
Warranty Period,  Ordering  Company notifies  Supplier of a defect covered under
paragraphs (a) and (b) above,  then Supplier shall commence to repair or replace
such Work within seven (7) days after receipt of written notice. Notwithstanding
the above, if the refund or credit option is not chosen and if Ordering  Company
notifies  Supplier  that the defective or  non-conforming  Work is of a critical
nature for network protection or for safety reasons,  Supplier shall commence to
repair or  replace  the Work  within  twenty-four  (24) hours  after  receipt of
written notice.

                  (d) The warranties provided in this Section 11.12 do not cover
repair for damages,  malfunctions or service  failures caused by: (i) actions of
any personnel not employed,  directly or indirectly,  by Supplier; (ii) Ordering
Company's  failure to follow Supplier's  installation,  maintenance or operation
instructions; or (iii) a condition of Force Majeure.

                  (e) THE WARRANTIES  STATED IN THIS SECTION 11.12
ARE EXCLUSIVE
AND ARE IN LIEU OF ALL OTHER EXPRESSED OR IMPLIED WARRANTIES,
INCLUDING BUT NOT
LIMITED TO WARRANTIES OF  MERCHANTABILITY  OR FITNESS FOR A
PARTICULAR  PURPOSE.
EXCEPT FOR (a) TANGIBLE  PROPERTY  DAMAGE AND PERSONAL INJURY FOR
WHICH SUPPLIER
IS HELD LIABLE AND (b) THE REMEDY PROVIDED IN SECTION 5.1(e),
ORDERING






COMPANIES' REMEDIES, ORDERING COMPANY'S SOLE AND EXCLUSIVE REMEDY
SHALL BE
SUPPLIER'S OBLIGATION TO REPAIR, REPLACE, MAKE CORRECTIONS OR
REFUND AS SET
FORTH ABOVE IN THIS WARRANTY.

                  (f) PRODUCT RELOCATION OR MODIFICATION. Ordering Company shall
advise  Supplier  promptly  of any change in  location  or  modification  to any
Product  covered by warranty  service under this Agreement.  If such change,  in
Supplier's opinion, creates a safety hazard or is likely to cause a malfunction,
Supplier  may at  Ordering  Company's  expense,  correct the  condition.  If the
condition cannot be corrected to Supplier's  reasonable  satisfaction,  Supplier
reserves the right to terminate  without  liability  warranty service under this
Agreement for the products relocated and/or modified.

                  11.13 SAFETY; EMERGENCY. (a) Supplier shall be
responsible for
the safety of the Work it performs; provided, however, that
Supplier shall not
be responsible for any unsafe circumstance caused by Ordering
Company or Others.

                  (b) Whenever, in the reasonable opinion of Ordering Company or
the Engineer,  Supplier has not taken  sufficient  precautions for the safety of
the public or the protection of the Work or adjacent structures or property, and
whenever,  in the  reasonable  opinion of Ordering  Company or the Engineer,  an
emergency has arisen and immediate action is considered necessary, then Ordering
Company,  with prior  notice to Supplier,  may provide  suitable  protection  by
causing Work to be done and material to be furnished  and placed.  To the extent
that Supplier is responsible  for such emergency,  the reasonable  out-of-pocket
cost of such Work and material  shall be borne by  Supplier,  and if the same is
not paid on presentation of the bills therefor,  such costs may be deducted from
amounts due or to become due Supplier.  The  performance  of such emergency Work
shall not relieve Supplier to the extent of its  responsibility for damage which
may  occur.  Ordering  Company  shall make a good  faith  effort to contact  and
utilize the  services of Supplier to correct the  emergency  protection  problem
prior to retaining the services of another contractor.

                  11.14  ENGINEER'S  DRAWINGS AND
SPECIFICATIONS.  (a) Supplier
will be furnished a sufficient  number of sets of Drawings
including  revisions
thereto and sufficient copies of the Specifications without
charge. All Drawings
and  Specifications  shall be returned to the Engineer  upon
completion  of the
Work.   Supplier   may  retain   sufficient   copies  to  perform
its  Warranty
administration.

                  (b) The Drawings shall be signed by Ordering
Company's
Representative and by Supplier.

                  (c) Supplier shall conduct a normal and customary check of all
dimensions,  elevations,  and  quantities  indicated  on the  Drawings and lists
furnished by the  Engineer.  If  Suppliers  discovers in the course of its work,
major discrepancies  between the Drawings and the conditions at the site, errors
or omissions in the Drawings,  and in the layout as given by stakes,  points, or
instructions,  Supplier shall notify the Engineer.  Supplier will not be allowed
to take






advantage of errors or omissions in the Drawings or other  Agreement  Documents.
Full  instructions  will be  furnished  by the  Engineer  should  such  error or
omission be  discovered,  and Supplier shall carry out such  instructions  as if
originally   specified;   provided,   however,  that  in  the  event  that  such
instructions  result in an increase  in  Supplier's  costs or in a  Construction
Delay (as defined in Section 11.20, CONSTRUCTION DELAY, below) in the Completion
Schedule,  Supplier  shall  be  entitled  to  reasonable  compensation  and,  if
necessary, an extension in the Completion Schedule.

                  11.15 REFERENCE  STANDARDS.  Reference to the standards of any
technical society,  organization,  or association, or to codes of local or state
authorities,  or AT&T EH&S  Practices  shall  mean the  latest  standard,  code,
Specification,  or tentative standard adopted and published, unless specifically
stated otherwise.  Since the Agreement will likely cover multiple years,  except
as otherwise  required by Section 6.20,  COMPLIANCE  WITH LAW,  Supplier will be
given  sufficient  time to assess and comply with new standards,  and to request
additional time and/or compensation for compliance.

                  11.16  RECORDS.   Supplier  shall  maintain  complete  records
including, but not limited to all labor and equipment hours, material purchased,
and Work  subcontracted  to other  parties.  The records  shall be maintained in
accordance with recognized  commercial  accounting  practices and in such manner
that  they  may be  readily  audited.  The  records,  including  all  supporting
documents,  shall be  available  at all  reasonable  times for audit by Ordering
Company both during the contract  period and for one year  following the date of
final  payment or until all  disputes,  if any,  between  Supplier  and Ordering
Company have been finally  resolved,  whichever  is later.  Supplier  shall also
maintain  weekly sheets,  showing all labor and equipment  employed and material
received.

                  (a)  Supplier  shall  maintain at the site where Work is being
performed or Supplier's  local  construction  office a file of current copies of
all Drawings,  Specifications,  and other Agreement  Documents and supplementary
data.

                  (b) Supplier shall create a timed and dated  pictorial  record
of the Site,  including  paths of ingress and  egress,  before and after Work is
performed for the purpose of precluding or settling claims.

                  11.17 UNFAVORABLE CONSTRUCTION CONDITIONS.  (a) During periods
of unfavorable weather, wet or frozen grounds, or other unsuitable  construction
conditions,  Supplier  shall  confine its  operations  to Work which will not be
affected  adversely  thereby.  No portion of the Work shall be constructed under
conditions  which  would  adversely  affect the quality or  efficiency  thereof,
unless special means or precautions are taken by Supplier to perform the Work in
a proper and satisfactory manner.

                  (b) If adverse weather  conditions are encountered by Supplier
or its subcontractor(s) which are abnormal for the location and time of year for
which such claim is made,  the  construction  schedule  shall be  extended by an
amount of time equal to the effect of






such adverse weather. If adverse weather is the basis of a claim by Supplier for
additional  time,  such claim shall be  documented  by Supplier and include data
substantiating  that weather  conditions were abnormal for the period of time in
question and Supplier could not have been  reasonably  anticipated  such adverse
weather  and  that  such  weather  conditions  had  an  adverse  effect  on  the
construction schedule.

                  11.18 ARCHAEOLOGICAL SITES; ENVIRONMENTAL
PROTECTION. (a)
Known archaeological, historical or cultural sites along the route
will be
indicated on the Drawings by the Engineer.

                  (b) If  archaeological,  historical or cultural  artifacts are
encountered during construction  anywhere along the route,  construction at that
location shall stop and the Engineer shall be promptly notified.  Supplier shall
not harm or disturb  such  artifacts  until  instructed  by Ordering  Company or
Engineer as to how to proceed. If an extended delay is anticipated, Supplier may
elect to move to  another  location  of Work.  Notwithstanding  anything  to the
contrary herein,  Demobilization and Remobilization or construction delay due to
unanticipated  archaeological  findings  shall  be a basis  for  extra  payment.
Ordering  Company shall be  responsible  for obtaining any necessary  permits in
order to continue Work in the affected area.

                  (c) Ordering  Company  shall  provide  Supplier with AT&T EH&S
Practices, including updates. At the end of each calendar year, Ordering Company
shall provide  Supplier a list of all AT&T EH&S Practices still in effect.  AT&T
EH&S  Practices  shall be deemed  applicable to the Work under a Work Order only
when  provided to  Supplier at or prior to the date of the Work Order.  Supplier
shall  at its  own  expense  comply  with  the  most  stringent  of:  applicable
governmental laws,  regulations,  ordinances,  rules, codes, orders,  guidances,
permits,  approvals;  applicable  easement  or  license  conditions;  applicable
Supplier  EH&S  practices;  and  applicable  AT&T EH&S  Practices  (collectively
"Applicable EH&S Requirements").

                  (d)  Supplier  shall be  deemed  the  generator  of all  waste
associated  with the Work and shall  dispose of that waste at its own expense as
set forth in Section 11.18(c),  ARCHAELOGICAL SITES;  ENVIRONMENTAL  PROTECTION,
above.  "Waste" shall include without limitation all hazardous and non-hazardous
substances  and  materials  associated  with the Work which are  intended  to be
discarded,  scrapped,  or recycled. It shall be presumed that all substances and
materials  associated  with the Work  that  are not  incorporated  into the Work
(including  without   limitation   damaged   components  or  tools,   leftovers,
containers,  garbage, scrap, residues or byproducts),  except for substances and
materials that Supplier or Ordering Company intend to use in their original form
in connection with similar work, are waste.

                  (e) In the event  conditions  are  discovered or created at or
near the site of the Work which may require (i)  investigation or remediation or
(ii)  unforeseen   measures  to  protect  the  environment,   health  or  safety
(collectively  "Adverse EH&S  Conditions"),  the party discovering the condition
shall  immediately  notify the other party. The party in the best position to do
so (or, if the parties are equally  situated,  Supplier)  will then  immediately
take reasonable






measures  temporarily to contain or otherwise avoid  exacerbation of or exposure
to the  conditions.  Unless Ordering  Company  affirmatively  notifies  Supplier
otherwise,  Supplier  shall also take such  other  actions  as  Applicable  EH&S
Requirements prescribe.

   

                  (f) In the event  Supplier's  failure to comply  with  Section
11.18(c),  ARCHAELOGICAL SITES;  ENVIRONMENTAL  PROTECTION,  above or Supplier's
negligence  or  willful  misconduct  was a not  insignificant  cause  of (i) the
Adverse EH&S  Conditions or (ii)  exacerbation  of the Adverse EH&S  Conditions,
Supplier shall indemnify and hold harmless  Ordering  Company and be responsible
for all costs associated with curing the Adverse EH&S  Conditions.  In all other
events Ordering  Company shall indemnify and hold harmless  Supplier from and be
responsible for all costs  associated  with curing the Adverse EH&S  Conditions.
    

                  11.19  REPORTING  DEFECTS.  (a) If any part of Supplier's Work
depends,  for its proper  execution  or  results,  upon the Work of any  Others,
excepting Subcontractors, Supplier shall inspect and promptly report to Ordering
Company's  Representative  any defects in the Work that render it unsuitable for
the proper execution or results,  and Supplier shall not proceed with that phase
of the Work until so authorized by Ordering Company's  Representative.  Ordering
Company may request and Supplier shall provide such reports in writing.

                  (b)  Supplier  shall be made aware of the  delivery  status of
Ordering Company  furnished  materials and of the progress of construction  Work
being performed under separate  contracts,  in each case as informed by Ordering
Company pursuant to (c) below.

                  (c)  Ordering  Company will  furnish  information  to Supplier
which may be available to it regarding the status of Ordering Company  furnished
materials or construction Work being performed under separate
contracts.

                  11.20 CONSTRUCTION DELAY. (a) Supplier will
complete all Work
on or before the Completion Date unless either Ordering Company
agrees to extend
that Date or Supplier is entitled to an extension pursuant to this
Agreement.

                  (b)  Ordering  Company  will  perform all of its  obligations,
including  provision  of labor and  materials  to be  furnished  by it in such a
manner so as not to delay the  progress of the Work (such being a  "Construction
Delay"),  and in event of its failure to do so, thereby causing loss to Supplier
or as a result of one or more of the  circumstances  set forth in paragraph  (c)
immediately below,  Ordering Company agrees that it will compensate Supplier for
such loss and, if necessary, reschedule the Completion Date to a mutually agreed
upon date. Supplier agrees that if Supplier shall delay the progress of the Work
in breach of its obligations hereunder and such delay causes Ordering Company to
sustain a loss,  then Supplier will  reimburse  Ordering  Company for such loss,
subject to the limitation of Supplier's liability set forth in Article 5 of this
Agreement.






                  (c)   Notwithstanding   anything  to  the   contrary  in  this
Agreement,  among the causes of "Construction Delay" for which Supplier shall be
compensated and the Completion  Date shall be rescheduled  pursuant to paragraph
(b) immediately above, are the following:

                           (i) Lack of Ordering Company Permits;

                           (ii) Lack of Ordering Company furnished
material;

                           (iii) Work stoppage by landowner;

                           (iv) Work stoppage by permitting agency
even though
         Supplier has met the requirements of the relevant permits;

                   (v) Railroad company denying access to the
      right-of-way or rail due to railroad's operations which
regulate the
                                Work conditions;

                           (vi) Work stoppage by Ordering Company
to implement
         new requirements, including changes to the Completion
Date or
         Completion Schedule;

                 (vii) Waiting for the presence of the Ordering
                             Company Representative;

                  (viii) Defective or damaged Ordering Company
                               furnished material;

                    (ix) Special Service Precautions per the
         Specifications; and

                 (x) Waiting for Engineer's written approval to
              proceed due to the interference of other contractors.

                  (d) Delay time is payable by Ordering Company for Construction
Delay for the reasons  set forth  above,  when  Supplier  is  prevented  from or
delayed in working on any contracted item that is available
to  Supplier.
Construction  Delay time will begin after Supplier has been denied access to the
Work or Ordering  Company has delayed the Work for an accumulated time in excess
of one (1) hour during a given normal working day.

                  (e) The term  "accumulated  time" shall include  discontinuous
amounts  of time and  shall  be  applied  to an  entire  crew.  For  example,  a
four-person crew that incurred a forty five (45) minute  Construction  Delay due
to a  permit  problem  and  then  later  in the same  working  day  incurred  an
additional Construction Delay for another reason, would begin Construction Delay
time for the crew after fifteen (15) minutes of the second  delay.  If a crew is
into  Construction  Delay  time at the end of a Work day and is  prevented  from
working on any  contracted  item  available  the next Work day and the condition
that caused the Construction  Delay still exists,  then Construction  Delay time
shall continue  without the requirement that it be in excess of one hour for the
second day.






                  (f) If  Supplier  is forced  to cease all or a portion  of its
operations due to lack of right-of-way, by reason of injunction against Ordering
Company  or  other  legal  obstacles,  or delay  in  Ordering  Company-furnished
material deliveries,  Ordering Company may request that Supplier move to another
site or to move off the project.  At Ordering Company's request,  Supplier shall
move from the portion of the  project  upon which he was  previously  engaged to
another point in the project  designated  by Ordering  Company or to an Ordering
Company  location  completely  off the project.  Supplier  shall at a later date
complete the Work left behind, when requested to do so by Ordering Company,  and
such Work shall be done at prices specified in the Proposal plus  Demobilization
and Remobilization.

                  11.21  NOTICE  OF  LABOR  DISPUTES.   Whenever   Supplier  has
knowledge  that any labor  dispute is delaying or  threatens to delay the timely
performance of the Work, Supplier shall promptly give notice thereof to Ordering
Company.  Supplier  shall  confirm the notice in writing  within  three (3) Work
days.

                  11.22  PERFORMANCE  AND PAYMENT BOND.  Ordering  Company shall
have the right to require  Supplier to furnish a bond for the full and  faithful
performance of the Work and for the payment of all bills,  debts and obligations
related to the Work. The bond shall be in such form,  principal  amount and with
such  sureties as may be required by Ordering  Company.  Ordering  Company shall
reimburse Supplier for the net premium on the bond upon receipt of the sureties'
bills to  Supplier.  Supplier  agrees  and  represents  that no amount  for bond
premium is included in the contract price.

                  11.23 APPLICATION FOR PAYMENT;  TERMS OF PAYMENT. (a) Supplier
shall render to Ordering  Company  Applications  for Payment for an amount based
upon the  quantities  of Work in a Work  Order  which  have  been  completed  by
Supplier during the monthly invoicing period,  unless billing is rendered sooner
pursuant to a written  modification  of this Section or for delay and disruption
compensation  or Special  Conditions  accrued as provided  for  elsewhere in the
Agreement.  Ordering  Company shall promptly approve the Application for Payment
within ten (10)  business  days or notify  Supplier of any disputed  items in an
Application  for Payment.  If at the expiration of such ten business day period,
Supplier does not receive written  approval or rejection from Ordering  Company,
the Application for Payment shall be deemed approved.

                  (b) The method of measurement, basis of payment and conditions
under  which  payments  for  Special  Conditions  are  made  can be found in the
Specifications.

                  (c) For  material  furnished  by  Supplier,  the same terms of
payment  shall apply as the terms which apply for  Services  billed by Supplier.
For Material  supplied by Ordering Company and ordered from Supplier pursuant to
another Article of this General  Purchase  Agreement (e.g., an Order for cable),
the  terms  of  payment  are set  forth in such  Article  or  elsewhere  in this
Agreement.






                  11.24  LIENS.  If as a  result  of  any  act
or  omission  of
Supplier,  any  lien is  filed  by a  Subcontractor  against
Ordering  Company,
Supplier shall cause the same to be discharged of record within  forty-five (45)
days after receipt of written notice thereof from Ordering Company.

                                   ARTICLE XII
                               CONSULTING SERVICES

                  12.1  GENERAL.  The  provisions  of this  Article  12 shall be
applicable  to the  furnishing  by Supplier to  Ordering  Company of  Consulting

                  12.2  STATEMENT  OF  WORK.  (a) From  time to time  hereafter,
Ordering Company may authorize Supplier to render to Ordering Company Consulting
Services  and  related  work  (hereinafter  "Work")  by  submitting  an Order to
Supplier or by entering into a Supplemental  Agreement  with Supplier.  All Work
conducted  by Supplier in  response to such an Order or  Supplemental  Agreement
shall be considered Work under this Article, and the terms and conditions hereof
shall govern.  Supplier  shall render all the Services  specified in the request
within the time allowed therein and shall meet all interim  deadlines set by the
parties.

                  (b) Supplier agrees that all information  provided to Ordering

Ordering  Company in a lawful and ethical manner.  Supplier shall not provide to
Ordering  Company any information  which has been provided to Supplier under the
terms  of a  written  or oral  non-disclosure  confidentiality  agreement.  Such
Information includes, but is not limited to, proprietary, confidential, or trade
secret  Information of a party that was obtained by Supplier  during  Supplier's
prior  employment by such party. In the performance of this Agreement,  Supplier
shall not at any time: (i) misrepresent itself or its status to any third party;
(ii)  provide a false or  deliberately  misleading  reason for  inquiries or the
collection of Information;  (iii) misstate the nature of its  relationship  with
Ordering  Company;  or (iv) use any  element of fraud,  dishonesty  or  criminal
conduct  in  connection  with  its  performance  under  this  Agreement  and the
provisions of this Section 12.2.

                  12.3 OWNERSHIP OF INFORMATION. (a) Ordering
Company
acknowledges that Supplier expressly reserves and retains sole
ownership in its
trademarks and all intellectual property, including its
copyrighted materials
(report formats, creative materials, etc.) and unique inventing
and research
systems and methodologies as utilized in performing work. None of
the above may
be kept, copied or utilized by Ordering Company in any manner.

                  (b) Except as expressly  set forth herein,  nothing  contained
herein shall be construed as conferring to either party by implication, estoppel
or otherwise  any license or right under any patent,  trademark,  service  mark,
trade dress,  indicia of origin,  copyright,  mask work protection right, or any
other intellectual  property right which is owned,  controlled by or licensed to
either party.






                  (c) The parties'  respective  ownership  interests,  up to and
including one hundred percent (100%),  in and rights to use information  used or
produced by Supplier to perform Consulting Services hereunder,  other than those
specified  above,  shall be  determined on a case by case basis in each Order or
Supplemental  Agreement pursuant to which Ordering Company purchases  Consulting
Services from Supplier.

                  12.4 EQUIPMENT  SUPPLIER.  Ordering  Company  warrants that no
current corporate  policy,  would give rise to Supplier or any of its Affiliated
Companies  being  disqualified,  as a  result  of  this  Agreement  or the  work
performed  under it,  from  bidding  upon or being  awarded a contract to supply
telecommunications  or  computer  equipment,  Software,  or related  Services to
Ordering Company.

                  12.5  ORDERING  COMPANY'S   RESPONSIBILITY.
In  addition  to
Ordering Company's responsibilities specified in Section 6.4, ORDERING COMPANY'S
RESPONSIBILITY,  Ordering  Company  shall,  at no  charge to  Supplier,  provide
Supplier with financial,  operational and technical information, data, technical
support,  personnel or assistance  as may  reasonably be required by Supplier to
fulfill its obligations under this Article.

                  12.6  WARRANTY.  Supplier  warrants to Ordering  Company  that
Services  will be  performed in a  professional  manner and in  accordance  with
Ordering Company's  specifications or those referenced in the Order and shall be
in accordance with such  requirements or restrictions as may be lawfully imposed
by governmental  authority.  If the Services prove to be not so performed and if
Ordering Company notifies  Supplier within a thirty (30) day period,  commencing
on the date of completion of the Service, at Ordering Company's option, Supplier
either will correct the nonconforming  Service for which Supplier is responsible
or render a full or prorated  refund or credit based on the original  charge for
the Services.


                                  ARTICLE XIII
                      PURPOSE AND ORGANIZATION OF PART III

                  13.1  PURPOSE  AND SCOPE OF PART III.  Part III sets forth the
specific  additional  terms  and  conditions  pursuant  to  which  the  Business
Communications  Systems unit of Supplier  ("BCS")  shall  provide,  and Ordering
Companies shall purchase or license, BCS Products, Licensed Materials (including
Software) and Services.  The terms and conditions that shall govern BCS sales to
Ordering  Companies  shall  be  Part I and  Part  III  of  this  Agreement,  any
applicable Supplemental Agreement,  the Pricing Agreement (LC3775D) or any other
governing  agreement  covering pricing,  except that Sections 1.3 and 1.4 of the
Pricing  Agreement shall govern in any event.  With respect to BCS Products used
in conjunction with AT&T's Network, additional provisions may be negotiated on a
case-by-case basis and set forth in Supplemental Agreements or Orders.

                  13.2 ORGANIZATION OF PART III. Part III is
organized as
follows:








                  (a) Article 14 sets forth the additional terms
and conditions
governing BCS's provision of Products;

                  (b) Article 15 sets forth the additional terms
and conditions
governing BCS's licensing of Licensed Materials; and

                  (c) Article 16 sets forth the additional  terms and conditions
governing BCS's provision of Maintenance, Installation and other Miscellaneous
Services.

                  13.3 ORDERS

                  (a) The term "Order" shall be defined as any Ordering  Company
request to purchase  Products,  to receive a license to use Licensed Material or
to  obtain  Services.  Such  requests  will be done on a BCS order  form  (e.g.,
Product Agreement,  Service  Agreement,  Purchase/Service  Agreement,  Equipment
Supplement,  Maintenance  Supplement,  or Change Order Form), Ordering Company's
Purchase Order Form or other mutually agreeable order form.

                  (b)   Subject   to   Section   2.2,   subsequent   Orders  for
modifications,  additions  or  changes  will  become  an  integral  part of this
Agreement when accepted by BCS.

                  (c) The  Customer  Contract  Return  Date is the date BCS must
receive from Ordering  Company an executed  Order.  If this date is not met, BCS
may reschedule the Delivery Date and/or  In-Service Date and BCS may, subject to
Ordering  Company's  consent,  change  the  prices  specified  on the  Order  or
confirmation of such Order.

                  (d) When  applicable  for an Order,  BCS and Ordering  Company
will agree upon all dates and activities required to meet the scheduled Delivery
Date for  Customer-installed  Products,  or the  scheduled  In-Service  Date for
BCS-installed  Products, and complete the Project Milestone and Responsibilities
document (a sample of which has been provided as Exhibit 13-1 of this Agreement,
which  document  shall be  incorporated  by reference into such Order under this
Agreement).  The installation  responsibilities of each party with respect to an

which is incorporated into this Agreement.

                  (e)  Subject  to Section  2.2,  Orders  for  modifications  or
additions to the Products  acquired  hereunder placed after the Delivery Date or
In-Service  Date (as  applicable for said Product) will be governed by the terms
and conditions of this Agreement when the Order is accepted by BCS.

                  13.4 PRICE AND DISCOUNTS. Prices and discounts
for BCS's
Products, Licensed Materials and Services shall be as shown in the
AT&T-BCS
Pricing Agreement.








                  13.5 BILLING AND PAYMENT

                  (a) This section overrides any inconsistent provisions in Part
1 and covers how BCS will invoice Ordering Company.

                  (b) For Products  that BCS  installs,  BCS will bill  Ordering
Company for the Product and installation charges on the In-Service Date, except
as provided in Section 14.4(b).

                  (c) For Ordering Company-installed  Products,
BCS will invoice
Ordering Company upon delivery.

                  (d) BCS will invoice recurring charges in
advance.

                  (e) Payment of invoices is due within  thirty (30) days of the
invoice date.  Restrictive  endorsements or other  statements on checks will not
apply.

                  (f) If Ordering  Company  does not  generally  pay in a timely
fashion,  the  parties  agree to review the billing  and  payment  processes  to
improve such processes.

                  13.6 HAZARDOUS  MATERIAL.  Ordering Company is responsible for
removal  of  any  hazardous  material  (e.g.,  asbestos)  or  correction  of any
hazardous condition that affects BCS's performance of Services. Services will be
delayed until Ordering Company removes or corrects any such hazardous  condition
with no penalty to BCS.

                  13.7 IDENTIFICATION CREDENTIALS.  Ordering Company may, at its
discretion, require BCS's employees and subcontractors to exhibit identification
credentials,  which  Ordering  Company  may  issue,  in order to gain  access to
Ordering  Company's premises for the performance of the work. If for any reason,
any of BCS's  employees or  subcontractors  are no longer  performing  work, BCS
shall  immediately  inform Ordering  Company's  Representative  in the speediest
manner  possible.  Notification  shall be  followed  by the prompt  delivery  to
Ordering Company's Representative of the identification  credentials involved or
a written statement of the reasons why the identification  credentials cannot be
returned.  Subject to Section 5.1 of this Agreement, BCS shall be liable for any
damage or loss sustained by Ordering Company if the  identification  credentials
are not returned to Ordering Company.

                                   ARTICLE XIV
                              PURCHASE OF PRODUCTS

                  14.1  GENERAL.  The  provisions  of this  Article  14 shall be
applicable  to the  purchase  of  Products  from BCS.  If Software is also to be
licensed  for  use  on a  purchased  Product,  or if a  Product  is  also  to be
engineered or installed by BCS, the  provisions of Articles 15 and 16 shall also
be applicable.







                  14.2 CHANGE  CONTROL DATE. The Change Control Date ("CCD") for
Orders,  is a date shown on the Order or confirmation  of the Order,  and is the
last date BCS will be required  to accept  changes to the  Products  ordered for
delivery  on  the  Delivery   Date  for   Customer-installed   Products  or  for
installation on the In-Service Date for BCS-installed  Products.  The CCD is the
date BCS accepts the Order or is deemed to have  accepted it pursuant to Section
2.2, unless a different date is shown on the Order or confirmation of the Order.
Changes to the original  Order received by BCS prior to the CCD must be approved
in writing by authorized  representatives  of both parties.  Changes to an Order
received  and  accepted by BCS after the CCD will be treated as separate  Orders
and may be delivered after the Delivery Date for Customer-installed  Products or
may be installed after the In-Service Date for BCS-installed  Products.  The CCD
for Orders for modifications or additions  addressed in this Section will be the
date BCS accepts the Order or is deemed to have  accepted it pursuant to Section
2.2.

                  14.3 ORDERING COMPANY-INSTALLED PRODUCTS.

                  (a) The "Delivery  Date" is the date BCS
delivers the Products
to the Ordering  Company's  facility as specified in an Order or
confirmation of
Order.

                  (b)  BCS  will  make  reasonable  accommodations  if  Ordering
Company requests a delay in the originally  scheduled  Delivery Date if Ordering
Company  gives BCS written  notice prior to the CCD. If Ordering  Company  gives
notice of a request for a delay in the originally  scheduled delivery date after
the CCD,  requests more than one delay in the Delivery Date prior to the CCD, or
causes a delay in the Delivery Date as a result of Ordering Company's failure to
meet  obligations  under  this  Agreement,  BCS may  cancel  the  Order and bill
Ordering  Company for  cancellation  charges as set forth in Part 1 of this GPA;
provided however, that BCS shall give Ordering Company fifteen (15) days written
notice of its  intention  to cancel the Order and to bill  cancellation  charges
pursuant  to this  Section  and shall not cancel the Order if  Ordering  Company
accepts  delivery  prior to the  expiration of such period.  In addition,  BCS's
notice  shall  include a  reasonable  estimate of the  anticipated  cancellation
charges.  Notwithstanding  the  foregoing  provisions  of this Section  14.3(b),
Ordering  Company  may  delay  delivery  one time for up to  thirty  (30)  days,
provided Ordering Company has given BCS seven (7) business days' notice prior to
the scheduled ship date.

                  (c) Shipping charges may be adjusted if Ordering
Company
changes the location for delivery.

                          14.4 BCS-INSTALLED PRODUCTS.

                  (a) This Section 14.4 overrides any inconsistent
terms in Part
1 of this Agreement.  For all BCS Products,  if BCS installs such
Products,  BCS
will notify Ordering Company that the Product is installed in good
working order
and complies with BCS's  standard  specifications  and any other
specifications
agreed to by the parties (the "In-Service Date"). For







BCS's DEFINITYPBX and Multimedia Messaging and Response ("MM&R") Products,  such
notice  will be in  writing  and  Ordering  Company  shall  have ten  (10)  days
following the  In-Service  Date (the  "Acceptance  Period") to test the DEFINITY
and/or MM&R Product and to determine  whether  Ordering  Company agrees with BCS
that such Product complies with the applicable specifications and warranties for
that  Product.  If Ordering  Company does not notify BCS in writing  during such
Acceptance   Period  of  any   non-conformities   to  the   applicable   product
specifications  and  warranties,  the Product will be deemed  accepted as of the
In-Service Date.

                  During the  Acceptance  Period,  Ordering  Company may conduct
appropriate tests and then shall either:  (a) accept the Product -- by providing
written  notice to BCS of that fact,  in which case the  Product  will be deemed
accepted  as  of  the  In-Service  Date;  or  (b)  if  non-conformities  to  the
specifications  or warranties  exist, so advise BCS in writing,  specifying such
non-conformities.  BCS shall promptly correct such  non-conformities  and notify
Ordering  Company that they were corrected.  The Product will be deemed accepted
by  Ordering  Company  upon  correction  of the  non-conformities  specified  in
Ordering Company's notice.

                  If  BCS  is  unable  to   correct   all  of  the   significant
non-conformities  described in Ordering Company's notice within thirty (30) days
of receipt of Ordering  Company's  notice,  Ordering  Company shall either:  (a)
accept the  Product,  in which case BCS will be  required to continue to correct
any outstanding  non-conformity;  or (b) Ordering Company may reject the Product
without  any  liability  and BCS will  refund  all  amounts  paid to BCS for the
returned Product plus transportation  charges from BCS' plant and return; or (c)
have the Product  replaced  by BCS as  promptly  as possible by giving  Ordering
Company  priority  over other  customers at no  additional  charge.  If Ordering
Company  elects to reject the  Product,  it must do so in  writing  and within a
reasonable time frame.

                  (b)  BCS  will  make  reasonable  accommodations  if  Ordering
Company requests a delay in the originally scheduled In-Service Date if Ordering
Company  gives BCS written  notice prior to the CCD. If Ordering  Company  gives
notice of a request for delay in the originally  scheduled In-Service Date after
the CCD,  requests more than one delay in the In-Service  Date prior to the CCD,
or  causes a delay in the  In-Service  Date as a result  of  Ordering  Company's
failure to meet its obligations (e.g., its obligations under Section 13.6) under
this  Agreement,  Ordering  Company and BCS will mutually  agree to either:  (i)
deliver the Products and commence billing as of the originally scheduled
In-Service  Date, in which case  installation  will be rescheduled at a mutually
agreeable time and additional installation charges may apply; or (ii) cancel the
Order and bill Ordering Company for cancellation  charges as set forth in Part 1
of this GPA.  Notwithstanding the foregoing  provisions of this Section 14.4(b),
Ordering  Company  may  delay  delivery  one time for up to  thirty  (30)  days,
provided Ordering Company has given BCS seven (7) business days' notice prior to
the scheduled ship date.

                  (c) For BCS-installed Products, BCS will perform a site survey
to identify Ordering Company's specific installation  requirements.  If the site
survey  cannot be  performed  prior to the  execution  of an  Order,  it will be
scheduled and conducted as soon as Ordering









Company's facilities are available. Upon completion of the site survey, BCS will
identify and  communicate to Ordering  Company any  additional  charges that may
apply.  If there were  additional  charges  identified  during the site  survey,
Ordering Company may cancel the Order without incurring  cancellation charges if
Ordering  Company  notifies  BCS in  writing  within  ten (10) days of  Ordering
Company's receipt of the notice from BCS of the additional charges.

                  (d) Installation and shipping charges may be
adjusted if
Ordering Company changes the installation location.

                  14.5 PRODUCT WARRANTY.

                  (a) BCS warrants  that as of the date title  passes,  BCS will
have the right to sell,  transfer  and assign  Products  and the title  conveyed
shall be good and Products shall be delivered  free from any security  interests
or any other liens or encumbrances.

                  (b) For purposes of Sections 14.5(b) through 14.5(g) only, the
term  "Product"  also includes the  Product's  associated  Software.  During the
warranty period,  BCS warrants to Ordering  Company that the Products  furnished
shall conform to and perform in accordance with BCS's standard specifications or
documentation  and any other mutually agreed  specifications.  In addition,  BCS
warrants to Ordering  Company that the Products shall be  merchantable  and free
from defects in design (except to the extent (i) designed by Ordering Company or
(ii) design  defects are caused by the presence in BCS's  Product of  substitute
components of Ordering Company's selection not recommended by BCS), material and
workmanship. BCS also warrants that the Products will be new, remanufactured, or
refurbished,  and that  installation  and other  services will be performed in a
first-class workmanlike manner.

                  (c) The  warranty  period  shall be  specified  on an Order or
confirmation  of the Order and shall  begin on the  Delivery  Date for  Ordering
Company-installed Products or on the In-Service Date for
BCS-installed Products.
However, for DEFINITY and/or MM&R Products, if in the course of acceptance tests
significant  problems  occur such that  acceptance  is delayed for more than ten
(10) days  following  Ordering  Company's  notice  concerning  such  significant
problems,  the warranty  period shall  commence  upon  acceptance.  The warranty
period shall be one year if none is specified  on the Order or  confirmation  of
the Order.

                  (d) (i)  Replacement  material shall be warranted as set forth
above in Section  14.5(b).  Repaired  material  shall be  warranted as set forth
above in Section 14.5(b) for the remainder of the original warranty period.

                     (ii) When BCS performs services under a
time-and-materials   Order,  replacement  and  repaired  material,  as  well  as
associated  services,  will be warranted  for ninety (90) days from the date the
work is completed.









                   (e)  If a  Product  (including  any  associated  Installation
Services)  does  not meet the  above  warranties  during  the  warranty  period,
Ordering  Company shall promptly notify BCS. BCS shall take the following action
promptly:

         (i)  Within  the first  sixty  (60)  days of the
warranty  period,  if
         Ordering Company notifies BCS of a defect or
non-conformity  that does
         not  appear  to be  curable  through  repair  or
replacement  within a
         reasonable  time period,  Ordering  Company  will be
entitled,  at its
         option,  to a refund of the Product's  purchase price
and  installation
         charges upon return of the Product. Should Ordering
Company seek such a
         refund, it will provide BCS such cooperation as necessary
to enable BCS
         to remove the Product from Ordering Company's  premises,
if necessary.
         Transportation  costs and risk of loss or damage  in
transit  shall be
         borne by BCS. In the event of such a refund,  Ordering
Company may also
         return  for  credit any other BCS  Products  intended
for use with the
         defective  Product  that  cannot be applied to another
use by Ordering
         Company and may cancel, without liability for
cancellation charges, any
         pending Orders for such Products.

         (ii) After sixty (60) days, BCS, at its option,  shall
attempt first to
         repair or replace  such  Product  without  charge or, if
not  feasible,
         refund the original  purchase price and  installation
charges.  In the
         event  of  such  refund,   Ordering  Company  shall
provide  BCS  such
         cooperation  as  necessary  to enable  BCS to remove the
Product  from
         Ordering Company's  premises,  if necessary.
Transportation  costs and
         risk of loss or damage in transit  shall be borne by BCS.
In  addition,
         in the event of such  refund,  Ordering  Company  may
also  return  for
         credit  any  other BCS  Products  intended  for use with
the  defective
         Product  that cannot be applied to another use by
Ordering  Company and
         may cancel,  without  liability for cancellation
charges,  any pending
         Orders for such Product.

                  (f) All  warranties  shall  continue  in full force and effect
notwithstanding  transfer  of  title  (except  for  title  to  their  associated
Software) to the Products by Ordering  Company,  so long as Ordering  Company or
its Affiliates  shall remain the user of the Product.  All warranties shall also
survive inspection, acceptance and payment.

                  (g) THE FOREGOING PRODUCT  WARRANTIES ARE
EXCLUSIVE AND ARE IN
LIEU OF ALL OTHER EXPRESS AND IMPLIED  WARRANTIES,  INCLUDING BUT
NOT LIMITED TO
WARRANTIES OF FITNESS FOR A PARTICULAR PURPOSE. EXCEPT FOR (1)
TANGIBLE PROPERTY
DAMAGE  AND  PERSONAL  INJURY  FOR WHICH BCS IS HELD  LIABLE  AND
(2) THE REMEDY
PROVIDED IN SECTION 5.1(E),  ORDERING  COMPANY'S SOLE AND
EXCLUSIVE REMEDY SHALL
BE BCS'S OBLIGATION TO REPAIR, REPLACE,  CREDIT, OR REFUND AS SET
FORTH ABOVE IN
THIS WARRANTY.










                  (h) Certain additional warranties with respect
to Software are
set forth in Section 15.8.

                  14.6 WARRANTY/POST-WARRANTY SERVICE EXCLUSIONS.

                  (a) EXCEPT AS STATED IN SECTION  14.5,  BCS,
ITS  SUBSIDIARIES
AND THEIR AFFILIATES,  SUBCONTRACTORS AND SUPPLIERS, MAKE NO
WARRANTIES, EXPRESS
OR IMPLIED,  AND SPECIFICALLY  DISCLAIM ANY WARRANTY OF FITNESS
FOR A PARTICULAR
PURPOSE.

                  (b) The warranty  provided in Section  14.5 and  post-warranty
service do not cover repair for damages or  malfunctions  caused by: (1) actions
of non-BCS  personnel or the  attachment  to the  Products of non-BCS  furnished
equipment  or  Software;   (2)  Ordering   Company's  failure  to  follow  BCS's
installation,   operation  or  maintenance   instructions,   including  Ordering
Company's  failure to permit  BCS timely  remote  access to  Ordering  Company's
Products;  (3) failure of products  not  serviced by BCS;  (4) abuse,  misuse or
negligent acts of non-BCS personnel;  or (5) Force Majeure conditions  following
delivery. In addition, BCS is not obligated to provide warranty or post-warranty
service if Ordering Company modifies the Software. If Ordering Company requests,
BCS will  perform  repair or other  services  not covered by this  Agreement  to
Ordering  Company's  BCS  Products  at the  mutually  agreed  to rates  for such
service.

                  (c)  Additional  charges  may apply if BCS  incurs  additional
costs  in  providing  warranty  or  post-warranty  services  as  a  result  of a
modification of Products.  Unless otherwise agreed, BCS shall not be responsible
to provide warranty or post-warranty  Maintenance  Services, if Ordering Company
has moved a Product without notifying BCS.

                  (d) BCS DOES NOT WARRANT UNINTERRUPTED OR
ERROR-FREE OPERATION
OF THE PRODUCTS AND BCS DOES NOT WARRANT THAT THE PRODUCTS WILL
PREVENT, AND BCS
WILL NOT BE  RESPONSIBLE  FOR,  UNAUTHORIZED  USE (OR  CHARGES
FOR SUCH USE) OF
COMMON  CARRIER  TELECOMMUNICATION  SERVICES OR FACILITIES
ACCESSED  THROUGH OR
CONNECTED TO PRODUCTS. ORDERING COMPANY MAY PURCHASE BCS'S TOLL
FRAUD PROTECTION
PRODUCTS OR OFFERINGS (E.G.,  DEFINITY TOLL FRAUD INDEMNITY OFFER) IF IT CHOOSES
TO DO SO, PROVIDED BCS CONTINUES SUCH OFFERING.

                  14.7  DOCUMENTATION.  BCS shall furnish to Ordering Company at
no additional charge and grant Ordering Company the right to use one copy of the
documentation   for  each  unit  of  the  Products  provided   hereunder.   Such
documentation  will be that  customarily  provided by BCS to its customers,  for
that  Product,  at no  additional  charge.  BCS shall also  furnish to  Ordering
Company the standard application and/or planning guide or a similar document, to
the extent BCS  provides  such a document for the  Product.  Such  documentation
shall be provided











prior to or  included  with the  shipment of the  Products  from
BCS to Ordering
Company.  Additional  copies of the  documentation  are
available  at  mutually
agreeable prices.

                  14.8  SPECIFICATIONS.  Upon  request,  BCS  shall  provide  to
Ordering Company,  at no charge, and grant Ordering Company the right to use and
reproduce a copy of BCS's  available  commercial  Specifications  applicable  to
Products ordered hereunder. In addition, a copy of BCS's Specifications shall be
provided with each unit.  Additional copies are available at mutually  agreeable
prices.

                  14.9  REGISTRATION  AND  RADIATION  STANDARDS.  When a Product
furnished  under this Part III is subject to Part 68,  Part 15 or any other part
of the Federal Communications Commission's Rules and Regulations, as they may be
amended from time to time,  (hereinafter  "FCC  Rules"),  BCS warrants that such
Product complies with the registration,  certification,  type-acceptance  and/or
verification standards of FCC Rules including, but not limited to, all labeling,
customer instruction requirements, and the suppression of radiation to specified
levels.  BCS shall also establish  periodic  ongoing  compliance  re-testing and
follow a Quality Control  program,  to assure that Product shipped complies with
the  applicable  FCC Rules.  BCS agrees to indemnify and save  Ordering  Company
harmless from any liability,  claims, or demands (including costs,  expenses and
reasonable attorney's fees on account thereof) that may be made because of BCS's
noncompliance  with the  applicable  FCC Rules.  BCS  agrees to defend  Ordering
Company, at Ordering Company's request, against such liability, claim or demand.
In addition, should Product which is subject to Part 15 of the FCC Rules, during
use generate harmful interference to radio communications,  BCS shall provide to
Ordering   Company   information   relating  to  methods  of  suppressing   such
interference and pay the cost of suppressing such interference or, at the option
of Ordering Company, accept return of the Product and refund to Ordering Company
the price paid for the Product less a  reasonable  amount for  depreciation,  if
applicable.  Nothing  in this  Section  14.9  shall be  deemed  to  diminish  or
otherwise limit BCS's obligations under any other Section of this Agreement.

                  14.10 MARKING.  All BCS Product furnished under this Agreement
shall be marked for  identification  purposes in accordance with mutually agreed
upon  marking  specifications.  Such  specifications  shall  be set  forth  in a
Supplemental  Agreement  or Order.  All such  Product  shall also be marked with
BCS's  model/serial  number.  This Section 14.10 does not reduce or modify BCS's
obligations under Section 4.4, TRADEMARKS, of this Agreement.










                                   ARTICLE XV
                                    SOFTWARE

                  15.1 GENERAL.

                  (a) The  provisions of this Article 15 apply to the furnishing
of Software by BCS to Ordering Company pursuant to this Agreement. The ownership
interests  and rights of the  parties in Custom  Software,  in  addition  to the
applicable  rights  set  forth  in  this  Article,  shall  be  established  on a
case-by-case basis in subsequent Supplemental Agreements.

                  (b) To the extent that any provision set forth in this Article
conflicts with any provision set forth elsewhere in this Agreement, this Article
shall control.

                  (c) Software in this Article means both Custom
Software and
Licensed Materials.

                  15.2 SOFTWARE LICENSE.

                  (a) BCS grants Ordering  Company a personal,  non-transferable
(except to the extent allowed in Section 15.2(d) below) and non-exclusive  right
to use, in object code form,  all Licensed  Materials and related  documentation
furnished under this Agreement. Title to and ownership of all Licensed Materials
shall remain with BCS or its suppliers.  This grant shall be limited to use with
the equipment  for which the Licensed  Materials was obtained or, on a temporary
basis, on back-up  equipment when the original  equipment is inoperable.  Use of
Licensed Materials on multiple  processors is prohibited unless otherwise agreed
to in  writing by BCS.  Ordering  Company  will not  reverse  assemble,  reverse
compile, disassemble or decompile the Licensed Materials to derive a source code
equivalent of the Licensed  Materials.  Ordering  Company will take  appropriate
action to  instruct  Ordering  Company's  employees  and  users of all  Licensed
Materials of Ordering Company's obligations under this Section.

                  (b) Ordering Company may make a reasonable number of copies of
Licensed Materials,  solely for the purpose of back-up or archival use. Any such
copy must contain the same  copyright  and other  notices and markings  that the
original Licensed Materials contains. Use of Licensed Materials on any equipment
other than that for which it was obtained or removal of Licensed  Materials from
the  United  States  or  other  country  in which  the  Licensed  Materials  was
originally  deployed  (without  written  consent  of  BCS,  which  will  not  be
unreasonably withheld), or reverse assembly, reverse compilation, disassembly or
decompilation of the Licensed Materials to derive a source code equivalent shall
immediately  and  automatically  terminate  the  license  with  respect  to  the
particular unit of the Licensed Materials. If Ordering Company commits any other
material breach of the Licensed Materials license, the conditions of Article 5A,
ARBITRATION;  DISPUTE  RESOLUTION shall apply. BCS's cancellation of the license
at issue shall be tolled pending the outcome of the Dispute Resolution  process.
Simultaneous with initial invocation of








such process, Ordering Company shall deposit and have held in escrow, until such
dispute is resolved,  an amount equal to the current market price of the license
in question.

                  (c) BCS may provide  Ordering Company with Software that bears
the logo or copyright of another  company.  If BCS provides such Software with a
"shrinkwrap"  or other license from the other company,  those terms apply rather
than the license terms in this Agreement. If Ordering Company requests, BCS will
give Ordering Company a copy of such other license terms before Ordering Company
orders the Software.

                  (d) If the equipment  purchased  hereunder is sold or assigned
to another  party,  BCS  requires  that the new owner or assignee  execute a new
Licensed  Materials license and pay the then current Licensed  Materials license
fee, if any. Upon written  request,  BCS will grant the new owner or assignee of
the equipment the right to use any related Licensed Materials,  provided the new
owner or assignee  agrees,  in writing,  to BCS's terms and  conditions and pays
BCS's then current Licensed Materials license fee. BCS shall seek to enforce its
rights in the first instance against the new owner or assignee. If the new owner
or assignee of the equipment refuses to execute a new Licensed Materials license
agreement  or pay the  applicable  Licensed  Materials  license  fee,  or if the
equipment is no longer to be used by Ordering  Company,  Ordering  Company shall
either return the Licensed  Materials,  together with any copies, or destroy the
Licensed Materials and all copies, and provide BCS with prompt written notice of
such  destruction.  Notwithstanding  the  preceding  provisions  of this Section
15.2(d),  Ordering  Company  may  transfer  the  Licensed  Materials  to another
Ordering Company in connection with a transfer of the associated equipment,  and
BCS will not charge the new Ordering  Company a Licensed  Materials  license fee
therefor.

                  15.3  SOFTWARE.  On the delivery  date,  BCS shall  furnish to
Ordering Company,  at the fee specified in the Order or Supplemental  Agreement,
at least the following basic items:

                  (a)  Object  Code  stored  in a  medium
compatible  with  the
equipment,  as described in BCS's  Specifications,  the
applicable  Supplemental
Agreement or the Order;

                  (b)  User  documentation   which  BCS  normally  furnishes  to
customers  with the Licensed  Materials at no  additional  charge,  and any user
documentation specified in the applicable Supplemental Agreement; and

                  (c) If appropriate and if not previously
provided, the
required machine configuration.

                  15.4  INSTALLATION  OF  SOFTWARE.  Where  Ordering  Company is
responsible  for  installation  of  Software,  BCS's sole  responsibility  is to
deliver the  Software to Ordering  Company on or before the  scheduled  Delivery
Date  specified  in the  Order or  Supplemental  Agreement.  However,  if BCS is
responsible  for such  installation,  BCS shall deliver the Software to Ordering
Company in sufficient time for it to be installed on or before the scheduled In-









Service Date  specified in the Order or  Supplemental  Agreement,  and BCS shall
complete its installation and associated testing on or before such date.

                  15.5 CENTRALIZED MAINTENANCE.  Ordering Company
may specify in
an Order that,  for  centralized  maintenance  purposes,  all
Software  changes,
including  Enhancements,  provided by BCS shall be provided only to the Ordering
Company's  Centralized  Support  Organization.  BCS  will,  in  that  event,  be
responsive to  maintenance  requests  which the Ordering  Company's  Centralized
Support  Organization issues. This Organization will be responsible for Software
application,  initial acceptance testing and distribution of the Software to all
licensed  installations.  BCS grants Ordering  Company the right to transmit the
Software  by means of data links from  Ordering  Company's  Centralized  Support
Organization to each licensed  installation.  BCS grants to Ordering Company, at
no  additional  fee, a license  to use a copy of the  Software  for  centralized
maintenance  purposes  only.  BCS shall  provide  this  maintenance  copy of the
Software in response to an Order  requesting same. The maintenance copy provided
to the Ordering Company's  Centralized Support Organization will be used only to
perform  systems or  application  support  functions for the Ordering  Company's
application programmers, except as provided hereinafter. If the maintenance copy
of the  Software  provided  pursuant to this  Section  15.5 or a copy thereof is
later incorporated by the Ordering Company's  Centralized  Support  Organization
into a Ordering Company system or application support Software, Ordering Company
shall notify BCS and shall pay BCS the current  applicable rate paid by Ordering
Company for use of the Software.

                  15.6  ENHANCEMENTS.  BCS shall  promptly  furnish to  Ordering
Company during the duration of the Order, at an agreed upon charge,  if any, all
Software  Enhancements and telephone technical  assistance made available by BCS
to  commercial  customers  and shall  promptly  provide to Ordering  Company any
revisions  to the basic  Software  items  defined in Section 15.3 to reflect the
Enhancements.  All  Enhancements  shall be  considered  Software  subject to the
provisions of the Order.  Ordering Company may incorporate the Enhancements into
the Software or continue  using previous  versions of the Software,  at Ordering
Company's  option.  Ordering  Company  may,  at any time and at its  discretion,
discontinue  maintenance of the Software.  BCS shall not charge Ordering Company
for Quality  Protection Plan Change Notices  (QPPCNs) during the warranty period
or during any contracted-for  post-warranty  maintenance period. If the QPPCN is
required for warranty or post-warranty  service, and Ordering Company elects not
to obtain the QPPCN,  continuation of warranty or  post-warranty  service may be
subject to additional charges.

                  15.7 TRAINING AND TECHNICAL SERVICE. BCS shall
provide such
assistance, advice and training at no additional charge, as it
normally provides
without charge to other customers.

                  15.8 SOFTWARE WARRANTY. BCS warrants to Ordering
Company all
of the following:









                  (a) The Software will be free from  significant  errors,  will
conform to and perform in accordance with the  Specifications  and will function
properly. The Media conveying the Software will be free from defects in material
and  workmanship.  The  Software  will  be  compatible  with  and may be used in
conjunction with other Software as described in the Specifications.  If an Order
states  that  the  Software  is to be  used  in  conjunction  with  certain  BCS
equipment,  the Software shall be compatible with that equipment.  The foregoing
warranties  extend to the future  performance of the Software and shall continue
for one year except as otherwise specified in a Supplemental Agreement or Order.

                  (b) Software-related Work will be performed in a
first-class,
workmanlike manner.

                  (c) With respect to BCS-developed Software,  there are no copy
protection or similar  mechanisms  within the Software which will, either now or
in the future,  interfere  with the grants made in this  Agreement or an Order .
With respect to non-BCS developed  Software,  BCS will use reasonable efforts to
insure  that  there are no copy  protection  or  similar  mechanisms  within the
Software which will, either now or in the future, interfere with the grants made
in this Agreement or an Order.

                  (d) Ordering Company shall have quiet enjoyment
of the
Software.

                  (e) As to  Software  for  which  BCS does not  solely  own all
intellectual property rights, BCS has full right, power and authority to license
the Software to Ordering Company as provided in this Agreement or an Order.

                  (f) If the  Software,  or any portion  thereof,  is or becomes
unusable,  totally,  or in any respect during the applicable warranty period, or
if the work  fails to meet the  warranties,  BCS will  reperform  work,  correct
errors,  defects and  nonconformities  and restore  the  Software to  conforming
condition free of significant  errors at no cost to Ordering Company.  Corrected
Software shall be warranted as set forth in this clause.

                  (g) The Software does not contain any malicious code, program,
or other internal component (e.g.  computer virus,  computer worm, computer time
bomb, or similar  component),  which could damage,  destroy,  or alter Software,
firmware, or hardware or which could, in any manner, reveal, damage, destroy, or
alter  any  data or other  information  accessed  through  or  processed  by the
Software  in any manner.  BCS shall  immediately  advise  Ordering  Company,  in
writing,  upon  reasonable  suspicion  or  actual  knowledge  that the  Software
provided  under  this  Agreement  or an Order may  result in the harm  described
above.

                  (h) All warranties shall survive inspection,
acceptance and
payment.

                  15.9 RELATED DOCUMENTATION. BCS shall furnish to
Ordering
Company, at no additional charge, and grant Ordering Company the
right to use
one copy of the related









documentation  for each unit of the  Software  furnished by BCS pursuant to this
Agreement for the sole purpose of operating and maintaining such Software.  Such
related  documentation will be that customarily provided by BCS to its customers
for such  Software,  consistent  with the  vintage,  options  and feature of the
system on which it operates.  Such related documentation shall be provided prior
to or included with provision of Software by BCS to Ordering Company. Additional
copies of the related  documentation  are available at prices set forth in BCS's
Price List.

                  15.10  NOTIFICATION OF DISCONTINUED  AVAILABILITY OF SOFTWARE.
BCS  shall  notify  Ordering  Company  at  least  one  (1)  year in  advance  of
discontinued  availability of the last standard Software generic.  For a minimum
of two (2) years after  discontinued  availability,  BCS will make  available to
